ABSTRACT
BACKGROUND AND AIMS: Excess body weight (EBW) is the most prevalent nutritional disorder among adolescents worldwide. Identifying determinants of EBW may help find new intervention strategies. Behavioral, socio-economic, educational and demographic correlates of EBW were examined in a population of Italian adolescents, separately for males and females. METHODS AND RESULTS: As many as 1039 male and 2052 female students (aged 16-19 ys) attending the last three years of different types of high-school of the Emilia-Romagna region in Italy were offered participation, with 552 males and 841 females being finally evaluated. The prevalence of EBW was 21.0% in males and 14.1% in females. Step-wise multivariate logistic regression analyses were performed showing that EBW was negatively related to energy intake in males (odds ratio for 100 kcal/day (OR) = 0.94, 95% confidence interval (CI): 0.89 to 0.98; P = 0.008), and to father's educational attainment (OR = 0.70, 95% CI: 0.52 to 0.95; P = 0.020), but positively related to parental obesity (OR = 2.80, 95% CI: 1.65 to 4.76; P < 0.001). In females, EBW was positively related to parental obesity (OR = 1.94, 95% CI: 1.15 to 3.29; P = 0.013), but negatively to mother's educational attainment (OR = 0.66, 95% CI: 0.45 to 0.97; P = 0.034) and type of attended school (OR = 0.66, 95% CI: 0.49 to 0.89; P = 0.007). Mother's occupation was also an independent determinant of EBW status in females (OR = 0.39, 95% CI: 0.18 to 0.85; P = 0.018 for being unemployed vs blue-collar). CONCLUSION: Parental obesity is associated with EBW in male and female adolescents. Importantly, we found sex differences in socio-economic and educational factors impacting on EBW, supporting possible distinct area of investigation.

OBJECTIVE: To assess whether sonographic diagnosis of fetal head position before instrumental vaginal delivery can reduce the risk of failed vacuum extraction and improve delivery outcome. METHODS: Randomised Italian Sonography for occiput POSition Trial Ante vacuum (R.I.S.POS.T.A.) is a randomized controlled trial of term (37 + 0 to 41 + 6 weeks' gestation) singleton pregnancies with cephalic presentation requiring instrumental delivery by vacuum extraction, which was conducted between April 2014 and June 2017 and involved 13 Italian maternity hospitals. Patients were randomized to assessment of fetal head position before attempted instrumental delivery by either vaginal examination (VE) alone or VE plus transabdominal sonography (TAS). Primary outcome was incidence of emergency Cesarean section due to failed vacuum extraction. A sample size of 653 women per group was planned to compare the primary outcome between the two groups. The sample size estimation was based on the hypothesis that the risk of failed vacuum delivery in the VE group would be 5% and that ultrasound assessment of fetal position prior to vacuum extraction would decrease this risk to 2%. RESULTS: On interim analysis, the trial was stopped for futility. During this period, 222 women were randomized and 221 were included in the final data analysis, of whom 132 (59.7%) were randomized to evaluation of fetal head position by VE only and 89 (40.3%) to assessment by VE plus TAS prior to vacuum extraction. No significant differences were observed between the two groups with respect to incidence of emergency Cesarean section due to failed instrumental delivery and other maternal and fetal outcomes. Women randomized to assessment by VE plus TAS showed higher incidence of non-occiput anterior position of the fetal head at randomization and lower incidence of incorrect diagnosis of occiput position compared with women undergoing assessment by VE alone. A higher rate of episiotomy was noted in the women undergoing both VE and TAS compared with those in the VE-only group. CONCLUSIONS: Our prematurely discontinued randomized controlled trial did not demonstrate any benefit in terms of reduced risk of failed instrumental delivery or maternal and fetal morbidity in women undergoing sonographic assessment of fetal head position prior to vacuum extraction.

STUDY QUESTION: Which is the best method for human ovarian tissue cryopreservation: slow freezing/rapid thawing (SF/RT) or vitrification/warming (V/W)? SUMMARY ANSWER: The conventional SF/RT protocol used in this study seems to better preserve the morpho-functional status of human cryopreserved ovarian tissue than the used open carrier V/W protocol. WHAT IS KNOWN ALREADY: Cryopreservation of human ovarian tissue is generally performed using the SF/RT method. However, reduction in the follicular pool and stroma damage are often observed. An emerging alternative procedure is represented by V/W which seems to allow the maintenance of the morphological integrity of the stroma. STUDY DESIGN, SIZE, DURATION: This is a retrospective cohort study including six patients affected by oncological diseases and enrolled from January to December 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS: Ovarian tissue was laparoscopically harvested from the right and left ovaries and was cryopreserved using a routinary SF/RT protocol or a V/W method, involving tissue incubation in two solutions (containing propylene glycol, ethylene glycol and sucrose at different concentrations) and vitrification in an open system. For each patient, three pieces from each ovary were collected at the time of laparoscopy (fresh tissue) and after storage (SF/RT or V/W) and processed for light microscopy (LM) and transmission electron microscopy (TEM), to assess the morphological and ultrastructural features of follicles and stroma, and for laser scanning confocal microscopy (LSCM), to determine the functional energetic/redox stroma status. The preservation status of SF/RT and V/W ovarian tissues was compared with that of fresh ones, as well as between them. MAIN RESULTS AND THE ROLE OF CHANCE: By LM and TEM, SF/RT and V/W samples showed cryodamage of small entity. Interstitial oedema and increased stromal cell vacuolization and chromatin clumping were observed in SF/RT samples; in contrast, V/W samples showed oocyte nuclei with slightly thickened chromatin and irregular shapes. The functional imaging analysis by LSCM revealed that the mitochondrial activity and intracellular reactive oxygen species levels were reduced both in SF/RT and in V/W samples compared with fresh samples. The study also showed progressive dysfunction of the mitochondrial activity going from the outer to the inner serial section of the ovarian cortex. The reduction of mitochondrial activity of V/W samples compared with fresh samples was significantly higher in the inner section than in the outer section. LIMITATIONS, REASONS FOR CAUTION: The results report the bioenergetic and oxidative status assessment of fresh and cryopreserved human ovarian tissue by LSCM, a technique recently applied to tissue samples. The use of LSCM on human ovarian tissues after SF/RT or V/W is a new application that requires validation. The procedures for mitochondrial staining with functional probes and fixing are not yet standardized. Xenografting of the cryopreserved ovarian tissue in severe combined immunodeficient mice and in vitro culture have not yet been performed. WIDER IMPLICATIONS OF THE FINDINGS: The identification of a cryopreservation method able to maintain the morpho-functional integrity of the ovarian tissue and a number of follicles comparable with those observed in fresh tissue might optimize results in clinical practice, in terms of recovery, duration of ovarian function and increased delivery outcomes after replanting. The SF/RT protocol allowed better morpho-functional tissue integrity than the V/W procedure. STUDY FUNDING/COMPETING INTERESTS: Funding was provided by Fondazione del Monte di Bologna e Ravenna, Italy.

AIM: In addition to the effects on glycemic control and body weight, GLP-1 receptor agonists may favorably affect other major cardiovascular disease (CVD) risk factors, although currently available data are still sparse. In this retrospective study, we evaluated the effects of 12-month treatment with liraglutide on major CVD risk factors in 115 type 2 diabetes outpatients (60 men and 55 women), on stable hypoglycemic, anti-hypertensive and/or lipid-lowering therapy. METHODS: Clinical and anthropometric data, metabolic and lipid profile, as well as the Visceral Adiposity Index (VAI), an obesity-related CVD risk factor, were measured in all participants at baseline and after 12-month treatment. RESULTS: Treatment with liraglutide was associated with a significant reduction from baseline values of fasting blood glucose (-42.1 mg/dl, P < 0.05), HbA1c (-1.5 %, -17 mmol/mol, P < 0.05), body weight (-7.1 kg, P < 0.05), waist circumference (-6.8 cm, P < 0.001), total-cholesterol (-27.4 mg/dl, P < 0.05), LDL-cholesterol (-25.4 mg/dl, P < 0.05), triglycerides (-56.1 mg/dl, P < 0.05), and non-HDL-C (-36.6 mg/dl, P < 0.05) and an increase of HDL-cholesterol concentrations (+9.3 mg/dl, P < 0.001), a significant reduction in both systolic and diastolic blood pressure (-14.7 mmHg, P < 0.001 and -9.0 mmHg, P < 0.05, respectively) and a decrease of VAI values (-1.6, P < 0.001). All these differences were independent of changes in BMI and comparable in men and women. CONCLUSIONS: In conclusion, 12-month treatment with liraglutide in add-on to on-going hypoglycemic therapy significantly ameliorates all major CVD risk factors and reduces cardiometabolic risk, as estimated by VAI values.

OBJECTIVES: The objectives of this study were firstly to assess the longitudinal changes of various sonographic parameters of fetal head progression in relation to length of active second stage of labor, and secondly to compare ultrasound findings obtained longitudinally among fetuses with persistent occiput posterior (OP) vs those with persistent occiput anterior (OA) position. METHODS: From a series of nulliparous low-risk women at term attending the labor ward of our university hospital, transperineal ultrasound volumes were prospectively acquired at the beginning of the active second stage (T1) and at 40-min intervals thereafter until delivery (T2, T3). Sonographic parameters were derived from offline analysis of each volume, including the angle of progression (AoP), progression distance (PD), head-symphysis distance (HSD), head direction (HD) and midline angle. These parameters were compared between patients who delivered within 60 min from the beginning of the active second stage of labor (early delivery) and those who remained undelivered by that time (late delivery). Fetal head position was determined from stored digital images of transabdominal examinations performed at the beginning of the active second stage. Comparison was performed between fetuses with OA and those with persistent OP position at delivery. RESULTS: Spontaneous vaginal delivery was achieved in 58 (81.7%) cases, whereas vacuum extraction and Cesarean section were performed in eight (11.3%) and five (7.0%) cases, respectively. Delivery was achieved within 60 min from the beginning of the active second stage in 44 (62.0%) patients. In the early vs late delivery groups, measurements of AoP, HSD and PD at T1 were significantly different (AoP, 143.9 ± 20.5° vs 125.3 ± 15.0°, P < 0.001; HSD, 14.8 ± 4.5 mm vs 20.9 ± 5.8 mm, P < 0.001; PD, 44.0 ± 14.1 vs 35.0 ± 13.1 mm, P = 0.008). On logistic regression analysis of data obtained at T1, maternal body mass index, oxytocin administration, neonatal birth weight and HSD appeared to predict independently duration of the active second stage. Among fetuses delivering in the OP position (n = 10, 13.5%), Cesarean delivery was significantly more common than in those delivering in the OA position (n = 5 (50.0%) vs n = 2 (3.1%), P = 0.001). Women with persistent OP position compared with OA showed a significantly different AoP at T1 (122 ± 17° vs 138 ± 20°, P = 0.016), HD and HSD at T1 (HD, 112 ± 17 mm vs 86 ± 19 mm, P < 0.001; HSD, 16.5 ± 5.4 mm vs 22.8 ± 6.6 mm, P = 0.008) and at T2 (HD, 120 ± 16 vs 82 ± 27 mm, P = 0.008; HSD, 12.6 ± 3.4 mm vs 18.5 ± 5.4 mm, P = 0.038). CONCLUSIONS: AoP, PD and HSD are significantly different between patients undergoing delivery before or after 60 min from the beginning of the active second stage of labor. Ultrasound parameters are among the significant predictors of duration of the active second stage. Moreover, in fetuses persisting in the OP position vs those delivering in the OA position, fetal head progression seems to differ at early phases of the active second stage.

OBJECTIVES: To assess the intermethod agreement between two-dimensional (2D) and three-dimensional (3D) transperineal ultrasound methods in measuring a new index of fetal head station (the fetal head-symphysis distance (HSD)) in active labor, and to assess potential factors that may affect their agreement. METHODS: HSD was measured by transperineal ultrasound in 86 women in active labor, once using a 2D and once using a 3D technique. 2D images were acquired first in 43 cases and 3D images were acquired first in the other 43 women. Intermethod agreement between 2D and 3D methods was analyzed by means of intraclass correlation coefficient (ICC) and Bland-Altman analysis. In addition, potential factors affecting the intermethod reproducibility were investigated including fetal occiput position, order of acquisition, fetal head station, stage of labor, maternal body mass index and use of epidural analgesia, using the ANOVA test to check for systematic bias and Levene's test for homoscedasticity. RESULTS: Good agreement was demonstrated between 2D and 3D measurements of HSD (ICC, 0.949 (95% CI, 0.914-0.984)). No evidence of systematic difference was shown between the two methods (average difference ± SD = 0.03 ± 2.29 mm; P = 0.888). The only factor that had a significant effect on systematic difference between 2D and 3D methods was order of acquisition (P = 0.042); the first observation was higher regardless of the method used. Fetal head station had a significant effect on the homogeneity between the two methods (P = 0.004) with a better 2D-3D agreement obtained at lower head stations (SD of differences: 1.63 vs 2.59 mm). CONCLUSIONS: There is very good agreement between 2D and 3D methods of assessing HSD. Agreement is better in lower fetal head stations.

OBJECTIVE: To compare longitudinal changes in angle of progression (AoP) and midline angle (MLA) during the active second stage of labor according to the mode of delivery. METHODS: A three-dimensional transperineal ultrasound volume was acquired in a series of nulliparous women at the beginning of the active second stage (T1) and every 20 min thereafter (T2, T3, T4, T5 and T6). Following delivery, all ultrasound volumes were analyzed and AoP and MLA were measured. RESULTS: Among 71 women included in the study, 58 underwent spontaneous vaginal delivery (group A) and 13 underwent operative delivery (group B) (eight by vacuum extraction and five by Cesarean section). When compared with Group B, Group A had a wider AoP only at T1 (140.0 ± 20.2° vs. 122.9 ± 16.7°; P = 0.010) and T2 (149.7 ± 20.7° vs. 126.9 ± 17.5°; P = 0.006). MLA was narrower in group A only at T3 (21.2 ± 11.7° vs. 40.8 ± 27.9°; P = 0.043), T4 (18.2 ± 15.0° vs. 47.4 ± 29.6°; P = 0.020) and T5 (18.3 ± 6.0° vs. 34.7 ± 4.2°; P = 0.034). On stepwise forward multiple logistic regression analysis, both AoP and MLA were independently associated with operative delivery (OR = 0.955 and OR = 1.018, respectively). CONCLUSION: Ultrasonographic assessment of fetal head descent in the second stage of labor may play a role in the prediction of the mode of delivery.

AIM: It has been shown that pro-adrenomedullin is a good marker of the severity of septic shock but there are no data on the early changes in serum pro-adrenomedullin concentrations in patients with shock. METHODS: Twenty-one patients with septic shock and 21 healthy subjects studied as controls. Serum concentrations of pro-adrenomedullin, procalcitonin, ferritin, CRP and IL-6 were determined in all subjects at the initial observation. Patients with septic shock were also studied after 24 and 48 hours. RESULTS: The concentrations of the acute phase proteins were significantly higher in patients with septic shock than in the control subjects during the entire study period (P<0.001). Only procalcitonin significantly decreased on the third day of observation with respect to both the first day (P=0.002) and the second day (P=0.006). Proadrenomedullin (P=0.017) and IL-6 (P=0.001) showed an AUC significantly different from the null hypothesis in differentiating the patients who survived and those who did not. The sensitivity and specificity of pro-adrenomedullin in the assessment of death were 71.4% and 72.7%, respectively, while IL-6 had a sensitivity of 92.9% and a specificity of 60.6%. CONCLUSION: Proadrenomedullin is a reliable prognostic marker in patients with shock; further studies on a more consistent number of septic patients will definitively assess whether proadrenomedullin may replace the current prognostic markers in critically ill patients with shock due to sepsis.

OBJECTIVE: Acoustic radiation force impulse (ARFI) is a new software-based technique that evaluates liver stiffness during B-mode ultrasonography. The purpose of this study was to evaluate the accuracy of ARFI in distinguishing patients with chronic autoimmune liver disease from healthy subjects. MATERIAL AND METHODS: We enrolled 9 adult patients (8 women, 1 man; age 48.1 ± 12.8 years) with chronic autoimmune disease (primary biliary cirrhosis (PBC, n = 3), autoimmune hepatitis (AIH, n = 2), primary sclerosing cholangitis (PSC, n = 1) and overlap syndromes, (n = 3) who underwent a liver biopsy and 11 healthy volunteers (age 34.7 ± 10.4 years; 7 women, 4 men). Liver stiffness was evaluated and expressed as the shear wave velocity (SWV) in m/sec. We used a US scanner Siemens-Acuson S2000, evaluating the right liver lobe and the left liver lobe. RESULTS: THE SWV WAS SIGNIFICANTLY HIGHER IN CASES (RIGHT LOBE: 1.51 ± 0.44; left lobe: 1.57 ± 0.40) than in controls (right lobe: 1.08 ± 0.10; left lobe: 1.12 ± 0.13) (right lobe: P = 0.002; left lobe: P = 0.013). We found no significant correlation between right and left lobe SWVs in cases (P = 0.779) or controls (P = 0.385). The SWV cut-off that best distinguished cases from controls was 1.25 m/sec (accuracy: AUC=0.885; sensitivity: 70.6%; specificity: 95.5%). CONCLUSIONS: ARFI elastography is a noninvasive ultrasonographic technique that can differentiate healthy subjects from patients with fibrotic stages of chronic liver disease.
ABSTRACT
BACKGROUND: Unlike chronic idiopathic intestinal pseudo-obstruction (CIIP), severe digestive syndromes that are not characterized by episodes resembling mechanical obstruction remain poorly characterized. The present study compared clinical features, small bowel motility, and quality of life (QoL) in patients with CIIP or severe functional gastrointestinal disorders (SFGID), compared to irritable bowel syndrome (IBS). METHODS: We enrolled 215 consecutive patients: 70 CIIP, 110 malnourished SFGID [body mass index (BMI) 17.8±1.8kg m(-2) ] and 35 non-malnourished SFGID (BMI 22.8±3.6kgm(-2) ). KEY RESULTS: Abnormal motor patterns that fulfilled diagnostic criteria for small bowel dysmotility were virtually absent in IBS patients, but were recorded in69 CIIP patients (98.6%), 82 malnourished SFGID patients (74.5%;), and 23 SFGID patients without malnutrition (65.7%) (P<0.0001). CIIP patients presented more frequently abnormal activity fronts, lack of response to feeding, and hypomotility than malnourished and non-malnourished SFGID patients (61.4%vs 42.7% and 31.4%, P<0.05 only vs non-malnourished SFGID; 8.6%vs 0.9% and 2.9%; 21.4%vs 0.9% and 0%, P<0.05). Quality of life mean scores were all significantly lower in CIIP patients and malnourished SFGID patients than in IBS. Bodily pain, general health, and vitality scores were lower in CIIP also compared to non-malnourished SFGID. CONCLUSIONS & INFERENCES: Chronic idiopathic intestinal pseudo-obstruction and SFGIDs are frequently associated with small bowel dysmotility and marked derangements of QoL which are significantly more severe than in IBS and result particularly in being severe in patients with recurrent sub occlusive episodes or inability to maintain a normal body weight.

OBJECTIVES: To evaluate the accuracy of three-dimensional (3D) ultrasound in fetal gender assignment in the first trimester. METHODS: A series of pregnant women attending at 11 to 13 + 6 weeks for the nuchal translucency (NT) scan were enrolled into the study. An ultrasound volume of each fetus was obtained and stored for offline analysis. On the reconstructed mid-sagittal plane, the angle between the genital tubercle and an imaginary line passing tangentially through the fetal back (genital angle) was estimated and a receiver-operating characteristics (ROC) curve was constructed to determine the best cut-off for genital angle in fetal male gender determination. Fetal gender was subsequently ascertained in all cases. To calculate the interobserver variability, a second operator repeated the measurements. RESULTS: There were 85 cases included in the study. The genital angle in males was significantly higher than that in females (51.2 ± 11.3° (n = 36) vs. 18.9 ± 4.1 (n = 49), P < 0.001). The ROC curve revealed the estimated genital angle to have a high degree of accuracy in fetal gender determination (area under the curve ± SE = 1.000 ± 0.001). The best cut-off for male gender determination was found to be between 27° and 29° (sensitivity, 100%; specificity, 98.0%). There was a high degree of correlation between the two operators (r(2) = 0.998; coefficient of variation = 5.4%). CONCLUSIONS: 3D ultrasound is a highly accurate and reproducible tool for fetal gender assignment prior to 14 weeks of gestation.

AIMS: To explore the quality of life in patients treated medically during the acute phase of pancreatitis as well as at 2 and 12 months after discharge from the hospital. PATIENTS: 40 patients were studied. The etiology of the pancreatitis was biliary causes in 31 patients and non-biliary causes in 9; mild disease was present in 29 patients and severe disease in 11. 30 patients completed the two surveys at 2 and 12 months after hospital discharge. METHODS: The SF-12 and EORTC QLQ-C30 questionnaires were used for the purpose of the study. RESULTS: The two physical and mental component summaries of SF-12, all the domains of EORTC QLQ-C30 (except for physical functioning and cognitive functioning) and some symptom scales of EORTC QLQ-C30 (fatigue, nausea/vomiting, pain, and constipation) were significantly impaired during the acute phase of pancreatitis. There was a significant improvement in the SF-12 physical component summary, and global health, role functioning, social functioning, nausea/vomiting, pain, dyspnea, and financial difficulties (EORTC QLQ-C30) at 2 months after discharge as compared to the basal evaluation. Similar results were found after 12 months except for the mental component score at 12-month evaluation, which was significantly impaired in acute pancreatitis patients in comparison to the norms. The physical functioning of the EORTC QLQ-C30 at basal evaluation was significantly impaired in patients with severe pancreatitis in comparison to patients with mild pancreatitis. CONCLUSIONS: Two different patterns can be recognized in the quality of life of patients with acute pancreatitis: physical impairment is immediately present followed by mental impairment which appears progressively in the follow-up period.

OBJECTIVE: To evaluate if cervical length predicts prepartum bleeding and emergency Cesarean section in cases of placenta previa. METHODS: Between September 2005 and September 2007, cervical length was measured by transvaginal ultrasound in women with complete placenta previa persisting into the third trimester of pregnancy. A complete follow-up of pregnancy was obtained in all cases. RESULTS: Overall, 59 women were included in the study group. The mean +/- SD gestational age at ultrasound was 30.7 +/- 2.7 weeks and the cervical length was 36.9 +/- 8.8 mm. Cesarean delivery was performed in all cases, at a mean gestational age of 34.7 +/- 2.3 weeks. Twenty-nine (49.1%) of the women presented prepartum bleeding and 12 (20.3%) required an emergency Cesarean section prior to 34 completed weeks due to massive hemorrhage. Cervical length did not differ significantly between cases with and those without prepartum bleeding (35.3 +/- 9.3 mm vs. 38.4 +/- 8.2 mm; P = 0.18), but was significantly shorter among patients who underwent emergency Cesarean section < 34 weeks due to massive hemorrhage compared with patients who underwent elective Cesarean section (29.4 +/- 5.7 mm vs. 38.8 +/- 8.5 mm; P = 0.0006). CONCLUSIONS: Transvaginal sonographic cervical length predicts the risk of emergency Cesarean section < 34 weeks in women with complete placenta previa.

Autoimmune pancreatitis is the pancreatic manifestation of a systemic inflammatory disease in which affected organs are characterized by intense lymphoplasmacytic infiltration. The diagnosis of autoimmune pancreatitis sometimes is puzzling and its differentiation from pancreatic cancer is a clinical challenge. The features of autoimmune pancreatitis are its typical histological pattern, imaging, serology (increase of immunoglobulins and the presence of autoantibodies), associated non-pancreatic organ involvement and response to steroid therapy. Recent advances in identifying these features have resulted in enhanced recognition, diagnosis of this benign disease and the avoidance of unnecessary surgical procedures for suspected malignancy. In this article, the authors will review recent updates in the steroid treatment of autoimmune pancreatitis.

BACKGROUND: SF-12 Health Survey, and European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30 are the two main questionnaires proposed and validated for assessing the quality of life in chronic pancreatitis. AIMS: To evaluate the role of the information furnished by both the SF-12 Health Survey and European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30 questionnaires, and to determine which of these two questionnaires may be considered more efficacious, in clinical practice, in describing the quality of life of patients with chronic pancreatitis. PATIENTS: We studied 163 consecutive patients with proven chronic pancreatitis. METHODS: The Italian version of the SF-12 Health Survey and the Italian neutral version of the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30 Version 3.0 questionnaires were administered. RESULTS: Pancreatic pain was the only clinical variable able to significantly impair the SF-12 Health Survey component summaries as well as all domains of the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30, while body mass index was positively related to the physical component summary-12 and to the domains of the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30. A high level of reliability of the domains/scores of the two questionnaires in evaluating the quality of life in patients with chronic pancreatitis was found and two main factors were identified. These two factors were mainly related to the two SF-12 Health Survey summary components. CONCLUSIONS: From a practical point of view, the SF-12 Health Survey is more reliable and easier to use in routine clinical practice than the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30.

BACKGROUND: Since the incidence of myocardial infarction and other cardiovascular ischaemic events is highest in early morning, on account of a relative hypercoagulable state occurring in this time period, an attempt was made to test whether reperfusion of the hepatic artery at this time of the day, at liver transplantation, produces an increased risk of early thrombosis. METHODS: The records of 255 consecutive patients receiving a first transplant for chronic liver disease were retrospectively analysed. As possible risk factors, for early post-operative thrombosis (<30 days from transplantation), several medical and surgical parameters were taken into consideration. Arterial reperfusion was considered to have taken place at a time of high coagulability when occurred between 6.00 a.m. and 10.00 a.m. on the basis of previous reports. RESULTS: Logistic regression identified donor age (OR for age >60: P=0.017), bench reconstruction of the artery (OR: 5.06, P=0.013) and time of high coagulability at reperfusion (OR 2.93, P=0.087), as independently associated with early hepatic artery thrombosis. CONCLUSIONS: The present findings identified three independent predictors of early hepatic thrombosis, warranting stricter post-surgical follow-up of patients presenting such conditions. Interestingly, these factors are consistent with arterial reperfusion in the early morning being associated with an increased risk of early hepatic artery thrombosis, suggesting relative coagulative imbalances to provide a contribution in the pathogenesis of this severe complication of liver transplantation.

BACKGROUND: More than half of all patients with pancreatic adenocarcinoma are over 70 years of age. Life expectancy for the elderly population is increasing and currently major pancreatic resection provides the only meaningful chance of cure for periampullary and pancreatic tumors. Controversy over what constitutes the correct treatment of these tumors in elderly patients continues to this day. The aim of our study was to determine whether age alone or age plus some prognostic factors constitute contraindications to major pancreatic resections. METHODS: Between 2000 and 2005, data from 88 consecutive patients who had major pancreatic resection for periampullary or pancreatic tumors were entered into a prospective database. Fifty-three patients under 70 years of age (young patients), and 35 patients 70 years of age or older (elderly patients) were compared with respect to several characteristics and the postoperative course. RESULTS: Postoperative mortality and morbidity, length of hospital stay, and long-term survival were similar in the two groups. In the elderly group, the mortality rate was significantly higher in patients with chronic obstructive pulmonary disease (COPD), and the morbidity rate was significantly higher in patients with ASA 3 than in patients with ASA 1-2, in whom a pancreaticoduodenectomy or total pancreatectomy had been performed. CONCLUSIONS: Age alone is not a contraindication for major pancreatic resection. In elderly patients a careful evaluation of the co-morbidities and of the type of surgical procedure is mandatory in order to allow the proper selection of those patients best suited for surgery in specialized centers.

BACKGROUND: Prolonged mechanical ventilation and the consequently long stay in the intensive care unit (ICU) appear to be important infection risk factors in patients undergoing liver transplant. METHODS: We analyzed the data relating to 70 liver transplants performed on 67 patients during the past year's activities. For each patient we have considered the presence of preoperative pulmonary alterations, the first radiological result of the postoperative thorax, the PaO(2)/FiO(2) ratio recorded in the peroperative phase immediately after induction of general anesthesia (T0), and arrival at the ICU at the end of the operation (T1). We also considered the enzyme trend (glutamate-oxalacetic transaminase [GOT] and glutamate-pyruvate transaminase [GPT]) recorded every 6 hours for the first 42 hours of the postoperative period (times T1 to T7). RESULTS: There was an evident correspondence between the values of PaO(2)/FiO(2) < or = 300 ratio at time T1 and the subsequent duration of mechanical ventilation (P = .001). There was also a correlation between the PaO(2)/FiO(2) < or = 300 ratio at time T1 and the trend of the GPT in the first 24 hours postsurgery (P = .021; P = .026; P = .018; P = .048) or GOT trend over the same span of time (P = .027; P = .035; P = .048). CONCLUSIONS: Graft malfunction as expressed by the enzyme trend affects both the duration of mechanical ventilation and the postoperative PaO(2)/FiO(2) ratios. This metric may be useful to reinforce infection surveillance and to perform an early percutaneous tracheostomy in these patients.

BACKGROUND: In clinical practice there is the need to utilise a time saving questionnaire to assess the quality of life. AIMS: To establish the validity of the SF-12 questionnaire in chronic pancreatitis patients and to identify the predictors capable of modifying the physical and mental summaries in these patients. QUESTIONNAIRES: SF-12 and SF-36 questionnaires were used. SUBJECTS: One hundred and forty-one outpatients with proven chronic pancreatitis. The data of 141 sex- and age-matched Italian subjects of two normative groups (61,434 Italian subjects for SF-12 and 2031 Italian subjects for SF-36) were used as controls. RESULTS: Chronic pancreatitis patients had the SF-12 physical and mental component summaries significantly related to the SF-36 physical and mental component summaries (P<0.001). The presence of pancreatic pain and non-pancreatic surgery accounted for 41.3% in the formation of the PCS-36 score and 37.2% in that of the PCS-12 score, respectively. Gender, BMI and pancreatic pain accounted for 15.3% of the information in the formation of the MCS-36 and for 14.7% in that of the MCS-12; using these clinical variables, the loss of information in applying the SF-12 instead of the SF-36 was very low (4.1 and 0.6% for the PCS and the MCS, respectively). CONCLUSIONS: The SF-12 is a good alternative to the SF-36 in assessing the quality of life in chronic pancreatitis.
