Cardiopulmonary Exercise Testing after Surgical Repair of Tetralogy of Fallot-Does Modality Matter?

BACKGROUND: Despite a successful repair of tetralogy of Fallot (rToF) in childhood, residual lesions are common and can contribute to impaired exercise capacity. Although both cycle ergometer and treadmill protocols are often used interchangeably these approaches have not been directly compared. In this study we examined cardiopulmonary exercise test (CPET) measurements in rToF. METHODS: Inclusion criteria were clinically stable rToF patients able to perform a cardiac magnetic resonance imaging (CMR) and two CPET studies, one on the treadmill (incremental Bruce protocol) and one on the cycle ergometer (ramped protocol), within 12 months. Demographic, surgical and clinical data; functional class; QRS duration; CMR measures; CPET data and international physical activity questionnaire (IPAQ) scores of patients were collected. RESULTS: Fifty-seven patients were enrolled (53% male, 20.5 ± 7.8 years at CPET). CMR measurements included a right ventricle (RV) end-diastolic volume index of 119 ± 22 mL/m2, a RV ejection fraction (EF) of 55 ± 6% and a left ventricular (LV) EF of 56 ± 5%. Peak oxygen consumption (VO2)/Kg (25.5 ± 5.5 vs. 31.7 ± 6.9; p < 0.0001), VO2 at anaerobic threshold (AT) (15.3 ± 3.9 vs. 22.0 ± 4.5; p < 0.0001), peak O2 pulse (10.6 ± 3.0 vs. 12.1± 3.4; p = 0.0061) and oxygen uptake efficiency slope (OUES) (1932.2 ± 623.6 vs. 2292.0 ± 639.4; p < 0.001) were significantly lower on the cycle ergometer compared with the treadmill, differently from ventilatory efficiency (VE/VCO2) max which was significantly higher on the cycle ergometer (32.2 ± 4.5 vs. 30.4 ± 5.4; p < 0.001). Only the VE/VCO2 slope at the respiratory compensation point (RCP) was similar between the two methodologies (p = 0.150). CONCLUSIONS: The majority of CPET measurements differed according to the modality of testing, with the exception being the VE/VCO2 slope at RCP. Our data suggest that CPET parameters should be interpreted according to test type; however, these findings should be validated in larger populations and in a variety of institutions.

Upper Gastrointestinal Endoscopy Quality in Italy: A Nationwide Study.

BACKGROUND AND AIMS: International guidelines advise improving esophagogastroduodenoscopy (EGD) quality in Western countries, where gastric cancer is still diagnosed in advanced stages. This nationwide study investigated some indicators for the quality of EGD performed in endoscopic centers in Italy. METHODS: Clinical, endoscopic, and procedural data of consecutive EGDs performed in one month in the participating centers were reviewed and collected in a specific database. Some quality indicators before and during endoscopic procedures were evaluated. RESULTS: A total of 3,219 EGDs performed by 172 endoscopists in 28 centers were reviewed. Data found that some relevant information (family history for GI cancer, smoking habit, use of proton pump inhibitors) were not collected before endoscopy in 58.5-80.7% of patients. Pre-endoscopic preparation for gastric cleaning was routinely performed in only 2 (7.1%) centers. Regarding the procedure, sedation was not performed in 17.6% of patients, and virtual chromoendoscopy was frequently (>75%) used in only one (3.6%) center. An adequate sampling of the gastric mucosa (i.e., antral and gastric body specimens) was heterogeneously performed, and it was routinely performed only by 23% of endoscopists, and in 14.3% centers. CONCLUSIONS: Our analysis showed that the quality of EGD performed in clinical practice in Italy deserves to be urgently improved in different aspects.

Differences in Physical Activity Levels between Healthy and Transplanted Children: Who Needs More Tips?

BACKGROUND: Advances in the medical-surgical field have significantly increased the life expectancy of patients undergoing solid organ transplantation but this exposes patients to long-term complications due to chronic therapies and changes in lifestyle. It is known that children affected by pathology tend to be more sedentary and inactivity represents a further risk factor for the onset of non-communicable diseases. The aim of the present study was to compare the lifestyle of two groups of young patients: one group of healthy subjects (HG) and one group of kidney or liver transplant recipients (TG). METHODS: Patients were asked to complete Physical Activity Questionnaire for Older Children (PAQ-C). RESULTS: A total of 104 subjects were recruited (50.9% male, mean age 12.8 ± 3.16 years old). No significant differences were observed in the final score between groups when comparing subjects based on health condition (Healthy 2.69 ± 0.65 vs. Transplant Group 2.42 ± 0.88), the intensity of sports activities (Competitive 2.82 ± 0.59 vs. Not Competitive 2.53 ± 0.7) or type of transplant (Liver 2.51 ± 0.91 vs. Kidney 2.16 ± 0.75). CONCLUSION: The results of this study showed a worrying reality: children are engaged in low levels of physical activity regardless of their health status and in general the level of activity does not reach the recommended values even in the absence of contraindications. So, it is necessary to encourage healthy children to practice more PA and to introduce PA prescriptions for transplanted children to prevent their health from deteriorating due to sedentariness.

Cardiopulmonary Exercise Testing in Children and Young Adolescents after a Multisystem Inflammatory Syndrome: Physical Deconditioning or Residual Pathology?

Multisystem inflammatory syndrome in children (MIS-C) is a serious health condition that imposes a long-term follow-up. The purpose of our pilot study is to evaluate the usefulness of the cardiopulmonary stress test (CPET) in the follow-up after MIS-C. All patients admitted for MIS-C in our hospital in the 12 months preceding the date of observation were considered for inclusion in the study. Pre-existing cardio-respiratory diseases and/or the lack of collaboration were the exclusion criteria. At enrolment, each subject passed a cardiological examination, rest ECG, echocardiogram, 24 h Holter-ECG, blood tests, and a CPET complete of spirometry. A total of 20 patients met the inclusion criteria (11.76 ± 3.29 years, 13 male). In contrast to the normality of all second-level investigations, CPET showed lower-than-expected peakVO2 and peak-oxygen-pulse values (50% of cases) and higher-than-expected VE/VCO2-slope values (95% of cases). A statistically significant inverse correlation was observed between P-reactive-protein values at admission and peakVO2/kg values (p = 0.034), uric acid values at admission, and peakVO2 (p = 0.011) or peak-oxygen-pulse expressed as a percentage of predicted (p = 0.021), NT-proBNP values at admission and peakVO2 expressed as a percentage of predicted (p = 0.046). After MIS-C (4-12 months) relevant anomalies can be observed at CPET, which can be a valuable tool in the follow-up after this condition.

Preliminary Evaluation of Sedentary Lifestyle in Italian Children after Solid Transplant: What Role Could Physical Activity Play in Health? It Is Time to Move.

BACKGROUND: Advances in the medical-surgical field have significantly increased survival after solid organ transplantation in the pediatric population. However, these patients are predisposed to the development of long-term complications (e.g., cardiovascular disease). The therapeutic role of physical activity (PA) to counteract these complications is well known. The purpose of the study was to investigate the level of PA in a pediatric population after solid organ transplantation. METHODS: In the first 4 weeks at the beginning of the school year, the Physical Activity Questionnaire for Older Children and Adolescents was administered to young patients who had previously undergone solid transplants at our institute. RESULTS: Questionnaires of 49 patients (57.1% female, mean age 13.2 ± 3.5 years) were analyzed and 32.7% of subjects did not perform any exercise during school physical education classes. Only 24% practiced a moderate quantity of exercise in the previous week (2-3 times/week) and 72% engaged in sedentary behaviors during weekends. CONCLUSIONS: Preliminary data confirmed that young recipients are still far from meeting the minimum indications of the World Health Organization on PA and sedentary behavior. It will be necessary to increase their involvement in PA programs in order not only to increase their life expectancy but also to improve their quality of life.

Re-evaluation After 2 Years of COVID-19 Pandemic: Return to Play in Pediatric Population: What's New?

An observational retrospective study was conducted on 180 young competitive athletes. These children were revaluated after a mild/moderate SARS-CoV-2 infection through 3 different kind of protocol aimed at recognizing any cardiorespiratory complications due to the infection. The aim of the present study was to evaluate the results of "return to play" Italian protocols for readmission to competitive sport in the pediatric population. All of the subjects analyzed were readmitted to competitive sports after revaluation. None of the young athletes showed cardiorespiratory compromises at first and/or second level evaluation, confirming that in young population there is low risk of hospitalization and life-threatening complications after a mild/moderate infection. Italian simplified protocol for resuming sport have proved to be a valuable tool for health assessment both in adult and young athletes allowing them to resume their training in safety.

Clinical high at-risk mental state in young subjects accessing a mental disorder prevention service in Italy.

We aim to assess how functioning, depressive symptoms, and psychotic symptoms are associated with different numbers of Clinical High At-Risk Mental State (CHARMS) categories. In this cross-sectional study, we assessed 62 help-seeking subjects aged 15-24 with a drop in functioning, with Structured Clinical Interview for DSM-5, Social and Occupational Functioning Assessment Scale (SOFAS), Comprehensive Assessment of At-Risk Mental State to define risk for psychosis, Hamilton Depression Rating scale (HAM-D), Positive and Negative Symptoms Scale, 6 items (PANSS-6). CHARMS criteria were assessed via retrospective chart review. Overall, 30.6% did not meet any CHARMS component criteria at baseline (CHARMS-), 27.4%, 33.9% and 8.1% met one, two, and three or more CHARMS groups. Overall, 48.8% met criteria for ultra-high risk for psychosis (17.7% without other CHARMS categories), 25.8% risk of borderline personality disorder (3.2% alone), 35.5% mild depression (8.1% alone), 11.3% risk of bipolar disorder (1.6% alone). SOFAS score and HAM-D score worsened from CHARMS- to three or more CHARMS categories, whilst PANSS-6 score did not. In a multivariate regression only PANSS-6 (beta=-1.105, p<0.001) was associated with SOFAS (R2=0.385). Help-seeking youth with poor functioning present symptoms meeting CHARMS criteria. Meeting criteria for multiple CHARMS categories is associated with increased depressive, but not psychotic symptoms, while psychotic symptoms play a prominent role in determining functional impairment. Results should be interpreted within the limitations of the study including the small sample size and the cross-sectional design, and need further replications.

Cardiopulmonary Exercise Testing in Repaired Tetralogy of Fallot: Multiparametric Overview and Correlation with Cardiac Magnetic Resonance and Physical Activity Level.

Patients with repaired Tetralogy of Fallot (rToF) typically report having preserved subjective exercise tolerance. Chronic pulmonary regurgitation (PR) with varying degrees of right ventricular (RV) dilation as assessed by cardiac magnetic resonance imaging (MRI) is prevalent in rToF and may contribute to clinical compromise. Cardiopulmonary exercise testing (CPET) provides an objective assessment of functional capacity, and the International Physical Activity Questionnaire (IPAQ) can provide additional data on physical activity (PA) achieved. Our aim was to assess the association between CPET values, IPAQ measures, and MRI parameters. All rToF patients who had both an MRI and CPET performed within one year between March 2019 and June 2021 were selected. Clinical data were extracted from electronic records (including demographic, surgical history, New York Heart Association (NYHA) functional class, QRS duration, arrhythmia, MRI parameters, and CPET data). PA level, based on the IPAQ, was assessed at the time of CPET. Eighty-four patients (22.8 ± 8.4 years) showed a reduction in exercise capacity (median peak VO2 30 mL/kg/min (range 25-33); median percent predicted peak VO2 68% (range 61-78)). Peak VO2, correlated with biventricular stroke volumes (RVSV: ß = 6.11 (95%CI, 2.38 to 9.85), p = 0.002; LVSV: ß = 15.69 (95% CI 10.16 to 21.21), p < 0.0001) and LVEDVi (ß = 8.74 (95%CI, 0.66 to 16.83), p = 0.04) on multivariate analysis adjusted for age, gender, and PA level. Other parameters which correlated with stroke volumes included oxygen uptake efficiency slope (OUES) (RVSV: ß = 6.88 (95%CI, 1.93 to 11.84), p = 0.008; LVSV: ß = 17.86 (95% CI 10.31 to 25.42), p < 0.0001) and peak O2 pulse (RVSV: ß = 0.03 (95%CI, 0.01 to 0.05), p = 0.007; LVSV: ß = 0.08 (95% CI 0.05 to 0.11), p < 0.0001). On multivariate analysis adjusted for age and gender, PA level correlated significantly with peak VO2/kg (ß = 0.02, 95% CI 0.003 to 0.04; p = 0.019). We observed a reduction in objective exercise tolerance in rToF patients. Biventricular stroke volumes and LVEDVi were associated with peak VO2 irrespective of RV size. OUES and peak O2 pulse were also associated with biventricular stroke volumes. While PA level was associated with peak VO2, the incremental value of this parameter should be the focus of future studies.

On the Implementation of Computerized Adaptive Observations for Psychological Assessment.

The use of observational tools in psychological assessment has decreased in recent years, mainly due to its personnel and time costs, and researchers have not explored methodological innovations like adaptive algorithms in observational assessment. In the present study, we introduce the behavior-driven observation procedure to develop, test, and implement observational adaptive instruments. In Study 1, we use a preexisting observational checklist to evaluate nonverbal behaviors related to psychotic symptoms and to specify the adaptive algorithm's model. We fit the model to observational data collected from 114 participants. The results support the model's goodness of fit. In Study 2, we use the estimated model parameters to calibrate the adaptive procedure and test the algorithm for accuracy and efficiency in adaptively reconstructing 58 nonadaptively collected response patterns. The results show the algorithm's good accuracy and efficiency, with a 40% average reduction in the number of administered items. In Study 3, we used real raters to test the adaptive checklist built with behavior-driven observation. The results indicate adequate intrarater agreement and good consistency of the observed response patterns. In conclusion, the results support the possibility of using behavior-driven observation to create accurate and affordable (in terms of resources) observational assessment tools.

Competitive sport after SARS-CoV-2 infection in children.

BACKGROUND: With the gradual resumption of sports activities after the lock-down period for coronavirus pandemic, a new problem is emerging: Allow all athletes to be able to return to compete after SARS-CoV-2 infection in total safety. Several protocols have been proposed for healed athletes but all of them have been formulated for the adult population. The aim of the present study is to evaluate the adequacy of Italian practical recommendations for return-to-paly, in order to exclude cardiorespiratory complications due to COVID-19 in children and adolescents. METHODS: Between April 2020 and January 2021 the Italian Sports Medical Federation formulated cardiorespiratory protocols to be applied to athletes recovered from SARS-CoV-2 infection. The protocols take into account the severity of the infection. Protocols include lung function tests, cardiopulmonary exercise test, echocardiographic evaluation, blood chemistry tests. RESULTS: From September 2020 to February 2021, 45 children and adolescents (aged from 9 to 18 years; male = 26) with previous SARS-CoV-2 infection were evaluated according to the protocols in force for adult. 55.5% of the subjects (N = 25) reported an asymptomatic infection; 44.5% reported a mild symptomatic infection. Results of lung function test have exceeded the limit of 80% of the theoretical value in all patients. The cardiorespiratory capacity of all patients was within normal limits (average value of maximal oxigen uptake 41 ml/kg/min). No arrhythmic events or reduction in the ejection fraction were highlighted. CONCLUSION: The data obtained showed that, in the pediatric population, mild coronavirus infection does not cause cardiorespiratory complications in the short and medium term. Return to play after Coronavirus infection seems to be safe but it will be necessary to continue with the data analysis in order to modulate and optimize the protocols especially in the pediatric field.

The Effects of Physical Inactivity and Exercise at Home in Young Patients with Congenital Heart Disease during the COVID-19 Pandemic.

Background: The COVID-19 pandemic had a significant impact on the population's ability to be physically active. Purpose: Evaluate the effect of the COVID-19 mitigation measures on exercise tolerance in patients with congenital heart disease (CHD). Materials and methods: All subjects (880, 6-18 years old) who performed a stress test at our hospital from October 2020 to February 2021 and had a similar test one year earlier were enrolled. A questionnaire on the degree of physical activity carried out in 2020 concerning the period prior to the pandemic was compiled. Exercise tolerance and the main anthropometric parameters between the first and second tests were compared. Results: 110 subjects (11.9 ± 4.1 years) were included in the study. The percentage of patients engaged in regular physical activity (RPA) decreased significantly during the pandemic (p < 0.001), and BMI increased significantly (p < 0.001), except among the subjects who began RPA during the lockdown, whereas test duration did not decrease significantly overall but increased in this last subgroup (p < 0.05) Conclusions: The COVID-19 lockdown led to a less active lifestyle with a significant increase in BMI in our group of CHD. These data could have negative effects on the risk profile of this population. RPA practiced at home seems to be effective in counteracting such effects.

Clinical presentation and need for treatment of a cohort of subjects accessing to a mental illness prevention service.

Outreaching activities decrease prognostic accuracy of at-risk mental state defining tools, over-attracting subjects who are not at increased risk of mental illness. The setting was a mental illness primary indicated prevention outpatients service embedded within the Psychiatry Unit of Padua University Hospital, Italy. Help-seeking patients accessing the service between January 2018 and December 2018 were evaluated with validated tools assessing functioning, at-risk mental state, schizotypal personality features, depressive and anxious symptoms, together with medical and family history collection. The primary outcome was the prevalence of drop in functioning at presentation according to the Social and Occupational Functioning Assessment Scale (SOFAS). Secondary outcomes were diagnoses according to DSM-5 criteria and meeting criteria for at-risk mental state. Fifty-nine patients accessed the service, mean age was 18.8 (2.12) years old, 54.2% were females. Virtually all subjects (97.7%) had a drop in functioning. Baseline primary diagnoses were depressive episode in 33%, anxiety disorder in 21%, personality disorder in 17%, adjustment disorder 9%, conduct disorder 7%, schizophrenia spectrum disorder 5%, bipolar disorder 5%, eating disorder in 1.7%, dissociative disorder 1.7%. Overall, 59.1% met at-risk mental state criteria. Lower functioning was associated with anxious symptoms (p=0.031), a family history of mental illness (p=0.045) and of suicide (p=0.042), and schizotypal personality traits (p=0.036). Subjects accessing a prevention service embedded within the mental health department already present a trans-diagnostic drop in functioning, mainly due to a non-psychotic mental disorder, with at-risk mental state in one patient out of two, and schizophrenia or bipolar disorder already present in only 10% of subjects. Prevention service within mental health facility setting appears to properly detect subjects in need of treatment with a drop in functioning, at risk of developing severe mental illness, without any outreaching activity in the general population.

Olfactory neuroepithelium alterations and cognitive correlates in schizophrenia.

BACKGROUND: Few studies have investigated alterations of olfactory neuroepithelium (ONE) as a biomarker of schizophrenia, and none its association with cognitive functioning. METHOD: Fresh ONE cells from twelve patients with schizophrenia and thirteen healthy controls were collected by nasal brushing, cultured in proper media and passed twelve times. Markers of cell proliferation (BrdU incorporation, Cyclin-D1 and p21 protein level) were quantified.Cognitive function was measured using Brief Neuropsychological Examination-2. PRIMARY OUTCOME: proliferation of ONE cells from schizophrenic patients at passage 3. Secondary outcome: association between alteration of cell proliferation and cognitive function. RESULTS: Fresh ONE cells from patients showed a faster cell proliferation than those from healthy controls at passage 3. An opposite trend was observed at passage 9, ONE cells of patients with schizophrenia showing slower cell proliferation as compared to healthy controls. In schizophrenia, overall cognitive function (Spearman's rho -0.657, p < 0.01), verbal memory - immediate recall, with interference at 10 s and 30 s (Spearman's rho from -0.676 to 0.697, all p < 0.01) were inversely associated with cell proliferation at passage 3. CONCLUSION: Fresh ONE cells collected by nasal brushing might eventually represent a tool for diagnosing schizophrenia based upon markers of cell proliferation, which can be easily implemented as single-layer culture. Cell proliferation at passage 3 can be regarded as a promising proxy of cognitive functioning in schizophrenia. Future studies should replicate these findings, and may assess whether ONE alterations are there before onset of psychosis, serving as an early sign in patients with at risk mental state.

Bupropion perceived as a stimulant by two patients with a previous history of cocaine misuse.

BACKGROUND AND OBJECTIVE: Despite animal studies having shown a generalisation of the bupropion cue to cocaine, this drug has been used in cocaine abuse with mixed results. We here aimed at describing two cases which contradict current knowledge. CASE REPORTS: We describe two cases of former cocaine abusers who reported a cocaine-like sensation upon taking bupropion. Bupropion improved patients' depression without any increase in cocaine craving. One of the patients increased without doctor consultation his dose on an as needed basis. CONCLUSIONS: The issue of bupropion cue generalisation to cocaine needs further elucidation. People with past cocaine addiction need to be informed on the potential of bupropion to elicit cocaine-like cues and be invited to adhere to medical prescription, because bupropion has been associated with fatalities in some cases.

Ribavirin priming improves the virological response to antiviral treatment in transplanted patients with recurrent hepatitis C: a pilot study.

INTRODUCTION: Patients with hepatitis C recurrence after liver transplantation represent a clinical challenge. Antiviral treatment in transplant patients has usually poor tolerability and limited efficacy, with a mean sustained virological response (SVR) of 30%. Our pilot study was aimed at evaluating whether 8-week ribavirin pre-treatment could increase either adherence or antiviral effect of a 48-week combination therapy. METHODS: Ribavirin pre-treatment (8 weeks) was started with 600 mg daily and increased to 10.4 mg/kg/day. After pre-treatment, 1.5 µg/kg/week pegylated interferon-α2b was added for 48 additional weeks of combination therapy. Blood count, liver function tests and plasma HCV-RNA were examined monthly. Ribavirin plasma concentrations were determined by HPLC. RESULTS: Thirteen patients (mean age 53±2 years, 11 males) were treated: eight were HCV genotype 1/4; five were genotype 2/3. The median baseline HCV RNA level was 6.5 log(10) (range 5.84-7.42 log(10)). During ribavirin pre-treatment the median HCV RNA levels decreased significantly (5.7 log(10) ; P=0.023). During combination therapy 6/13 (46%) patients exhibited a rapid virological response (RVR) and 10/13 (77%) patients a complete early virological response, two were non-responders. A decline of 0.5 log(10) HCV RNA during pre-treatment predicted RVR. SVR occurred in six patients (46%): four were genotype 2/3. Stable ribavirin dose reduction was required in only two patients (15%) in whom transient interferon reduction was also required. CONCLUSION: This proof-of-concept study indicates that ribavirin pre-treatment increased the tolerability of the antiviral treatment, and improved its efficacy in liver transplant patients. Moreover, the degree of HCV RNA decline during pre-treatment allowed one to predict on-treatment response.

Nutritional status: its influence on the outcome of patients undergoing liver transplantation.

BACKGROUND: Malnutrition is frequently present in case of end-stage liver diseases, and in cirrhotic patients, a poor nutritional status is considered to be one of the predictive factors for increased morbidity and mortality rates after surgery. The impact of the recipients' malnutrition on the outcome of liver transplantation (LT) is still under debate and recent studies have shown controversial results. PATIENTS AND METHODS: We prospectively analysed the nutritional status of 38 consecutive patients undergoing LT in our University Hospital. Subjective global nutritional assessments (SGA) and anthropometry were used for the evaluation of the nutritional status. Energy expenditure, dietary intake and energy balance were also evaluated. After LT, multiple short-term outcomes that could be influenced by the nutritional status, such as number of episodes of infections (bacterial, viral and fungal) until discharge from hospital, length of stay in intensive care unit (ICU), length of hospital stay and in-hospital graft and patient's survival, were recorded. RESULTS: Malnutrition was identified in 53% of cases according to the SGA. Pretransplant nutritional status, haemoglobin levels and disease severity were independently associated with the number of infection episodes during the hospital stay. The presence of malnutrition was the only independent risk factor for the length of stay in the ICU and the total number of days spent in hospital. CONCLUSION: The present data suggest that recipients' malnutrition should be taken into account as a factor that increases complications and costs after LT.

Worse recent efficacy of antiviral therapy in liver transplant recipients with recurrent hepatitis C: impact of donor age and baseline cirrhosis.

We hypothesized that antiviral efficacy [sustained virologic response (SVR)] has improved in recent years in the transplant setting. Our aim was to assess whether the efficacy of pegylated interferon (PegIFN)-ribavirin (Rbv) has improved over time. One hundred seven liver transplant patients [74% men, 55.5 years old (range: 37.5-69.5), 86% genotype 1a or 1b] were treated with PegIFN-Rbv for 355 (16-623) days at 20.1 (1.7-132.6) months after transplantation. Tacrolimus was used in 61%. Sixty-seven percent had baseline F3-F4 (cirrhosis: 20.5%). Donor age was 49 (12-78) years. SVR was achieved in 39 (36.5%) patients, with worse results achieved in recent years (2001-2003: n = 27, 46.5%; 2004: n = 23, 43.5%; 2005: n = 21, 35%; 2006 to January 2007: n = 36, 24%; P = 0.043). Variables associated with SVR in the univariate analysis included donor age, baseline viremia and cirrhosis, bilirubin levels, rapid virologic response and early virologic response (EVR), premature discontinuation of PegIFN or Rbv, and accumulated Rbv dose. In the multivariate analysis, the variables in the model were EVR [odds ratio (OR): 0.08, 95% confidence interval (CI): 0.016-0.414, P = 0.002] and donor age (OR: 1.039, 95% CI: 1.008-1.071, P = 0.01). Variables that had changed over time included donor age, baseline viremia, disease severity (cirrhosis, baseline bilirubin, and leukocyte and platelet counts), interval between transplantation and therapy, and use of growth factors. In the multivariate analysis, variables independently changing were donor age (OR: 1.041, 95% CI: 1.013-1.071, P = 0.004), duration from transplantation to antiviral therapy (OR: 1.001, 95% CI: 1.000-1.001, P = 0.013), and baseline leukocyte count (OR: 1.000, 95% CI: 1.000-1.000, P = 0.034). In conclusion, the efficacy of antiviral therapy with PegIFN-Rbv has worsened over time, at least in our center. The increase in donor age and greater proportion of patients treated at advanced stages of disease are potential causes.

The validation of the Italian Perceived Disability Scale (IPDS) in chronic daily headache sufferers.

The goals of this study were to assess the validity and usefulness of a new scale and to assess disability in a sample of patients with chronic daily headache. Participants were a convenience sample of 61 adult outpatients admitted to the Department of Medical Sciences of the Sant'Andrea Hospital in Rome, between September 2007 and May 2008. Inclusion criteria were, a diagnosis of chronic daily headache (illness duration >5 years). Patients were administered the Beck Hopelessness Scale (BHS), a specific section of the Mini-International Neuropsychiatric Interview (MINI) assessing suicidal intent, the Gotland Male Depression Scale (GMDS), and a scale devised to measure the degree of disability caused by the headache [Italian Perceived Disability Scale (IPDS)]. Analyses indicated that the IPDS had good internal consistency (Cronbach alpha = 0.93; average inter-item correlation = 0.40), and good convergent validity, with moderate to strong associations with measures assessing emotional distress (BHS, r = 0.47; P < 0.0001; GMDS, r = 0.72; P < 0.001). A single-item, logistic regression analysis indicated that the IPDS is able to predict suicide intent (Wald chi(2) = 5.04; P < 0.05) in chronic daily headache patients. The IPDS is a brief instrument that is useful for comparisons with other chronic illnesses, and it may be used both for basic research and clinical applications when screening for comorbidity with emotional distress and disorders.

Mental turmoil, suicide risk, illness perception, and temperament, and their impact on quality of life in chronic daily headache.

To evaluate the relationship among quality of life, temperament, illness perception, and mental turmoil in patients affected by chronic daily headache with concomitant medication overuse headache. Participants were 116 consecutive adult outpatients admitted to the Department of General Medicine of the Sant'Andrea Hospital in Rome, between January 2007 and December 2007 with a diagnosis of chronic daily headache (illness duration >5 years). Patients were administered the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-autoquestionnaire version (TEMPS-A), the Beck Hopelessness Scale (BHS), the Hamilton Rating Scale for Depression (HAM-D), the Mini-International Neuropsychiatric Interview (MINI), the Revised Illness Perception Questionnaire (IPQ), the Suicide Score Scale (SSS), and the Quality of Life Index (QL-Index). Twenty-eight percent of the patients evidenced moderate to severe depression, and 35% evidenced severe hopelessness. Analyses also indicated that quality of life, temperament, illness perception, and psychological turmoil are associated. However, a hierarchical multivariate regression analysis with quality of life as dependent variable indicated that only a model with mental turmoil variables may fit data; further, only the MINI suicidal intent resulted associated with quality of life (standardized regression coefficient = -0.55; t = -3.06; P < 0.01). Suicide risk may play a central role in affecting the quality of life of patients with chronic headache. The investigation of the interplay of factors that precipitate suicide risk should include assessment of chronic headache and its effects on wellbeing.

The natural history of portal hypertensive gastropathy in patients with liver cirrhosis and mild portal hypertension.

BACKGROUND: Portal hypertensive gastropathy is a potential cause of bleeding in patients with liver cirrhosis. Studies on its natural history have often included patients submitted to endoscopic or pharmacological treatment for portal hypertension. PATIENTS AND METHODS: A total of 222 cirrhotic patients with mild degree of portal hypertension (i.e., with no or small varices at entry, without previous gastrointestinal bleeding and medical, endoscopic, or angiographic treatment) were followed up with upper endoscopy every 12 months for 47 +/- 28 months. RESULTS: Upon enrollment 48 patients presented portal hypertensive gastropathy (43 mild and 5 severe) and the presence of esophageal varices was the only independent predictor of the presence of this gastric lesion at multivariate analysis. The incidence of portal hypertensive gastropathy was 3.0% (1.1-4.9%) at 1 yr and 24% (18.1-29.9%) at 3 yr, while the progression was 3% (1-6.9%) at 1 yr and 14% (4.2-23.8%) at 3 yr. The presence of esophageal varices and the Child-Pugh class B or C at enrollment were predictive of the incidence of portal hypertensive gastropathy, while only Child-Pugh class B or C was correlated with the progression from mild to severe, at multivariate analysis. During follow-up 16 patients bled from portal hypertensive gastropathy (9 acutely and 7 chronically) and one patient died of exsanguination from this lesion. CONCLUSIONS: The natural history of portal hypertensive gastropathy is significantly influenced by the severity of liver disease and severity of portal hypertension. Acute bleeding from portal hypertensive gastropathy is infrequent but may be severe.
