Abstract
BACKGROUND: Due to paucity of literature data, we aimed at evaluating the prognostic role of the ratio of tricuspid annular plane systolic excursion (TAPSE) to systolic pulmonary artery pressure (SPAP) in idiopathic pulmonary fibrosis (IPF) patients without severe pulmonary hypertension and at assessing its correlation with effective arterial elastance index (EaI). METHODS: Multi-instrumental data obtained in 60 IPF patients (73.2 ± 6.8 years) and 60 matched controls were retrospectively analysed. Primary endpoint was all-cause mortality, while secondary endpoint was the composite of all-cause mortality and re-hospitalisations for all-causes over medium-term follow-up. RESULTS: ;At baseline, TAPSE/SPAP was significantly lower in patients with IPF than in controls (0.36 ± 0.25 vs. 0.77 ± 0.18 mm/mmHg; P < 0.001). TAPSE/SPAP was inversely correlated with EaI (r = -0.96) in IPF patients. During follow-up (3.5 ± 1.5 years), 21 patients died and 25 were re-hospitalised due to cardiopulmonary causes. TAPSE/SPAP was independently associated with both primary (HR 0.79, 95%CI 0.65-0.97) and secondary (HR 0.94, 95%CI 0.92-0.97) endpoints. A TAPSE/SPAP ratio of <0.20 and <0.44 mm/mmHg showed the greatest sensitivity and specificity for predicting primary (AUC 0.98) and secondary (AUC 0.99) endpoints, respectively. CONCLUSIONS: TAPSE/SPAP is a strong predictor of adverse outcomes in mild-to-moderate IPF. The strong correlation between TAPSE/SPAP and EaI might be an expression of a systemic fibrotic process which involves the heart, lungs and circulation.

Abstract
The Double Asteroid Redirection Test (DART) had an impact with Dimorphos (a satellite of the asteroid Didymos) on 26 September 20221. Ground-based observations showed that the Didymos system brightened by a factor of 8.3 after the impact because of ejecta, returning to the pre-impact brightness 23.7 days afterwards2. Hubble Space Telescope observations made from 15 minutes after impact to 18.5 days after, with a spatial resolution of 2.1 kilometres per pixel, showed a complex evolution of the ejecta3, consistent with other asteroid impact events. The momentum enhancement factor, determined using the measured binary period change4, ranges between 2.2 and 4.9, depending on the assumptions about the mass and density of Dimorphos5. Here we report observations from the LUKE and LEIA instruments on the LICIACube cube satellite, which was deployed 15 days in advance of the impact of DART. Data were taken from 71 seconds before the impact until 320 seconds afterwards. The ejecta plume was a cone with an aperture angle of 140 ± 4 degrees. The inner region of the plume was blue, becoming redder with increasing distance from Dimorphos. The ejecta plume exhibited a complex and inhomogeneous structure, characterized by filaments, dust grains and single or clustered boulders. The ejecta velocities ranged from a few tens of metres per second to about 500 metres per second.

Abstract
OBJECTIVE The purpose of the study is to assess body hydration in patients with posterior vitreous detachment (PVD) by bioelectrical impedance analysis (BIA). PVD, one of the most common eye diseases, is associated in both research and the collective image with reduced daily water intake, but this finding is not supported by strong evidence in the literature. PATIENTS AND METHODS Based on Spectral Domain Optical Coherence Tomography (SD-OCT) evaluation, different PVD stages are identified: absent posterior vitreous detachment, partial posterior vitreous detachment (P-PVD), or complete posterior vitreous detachment (C-PVD). BIA is a simple, non-invasive bedside method used to assess body composition. Patients underwent BIA and completed a floaters symptoms. 30 patients were enrolled and divided into two groups according to the degree of vitreous detachment, in P-PVD (n=12) and C-PVD (n=18). Patients underwent BIA and completed a floaters symptoms questionnaire. BIA measured the Resistance (R), Reactance (Xc), Phase Angle (PhA), Total Body Water (TBW), Extracellular Water (ECW), Fat Mass (FM), Fat-Free Mass (FFM), and Body Cell Mass Index (BCMI). Finally, patients received a test to assess adherence to the Mediterranean diet (Mediterranean Diet Test Score, MDTS) with the addition of daily water intake. RESULTS Relevant data were obtained from the BIA evaluation: the values of R and Xc were lower in the P-PVD group than C-PVD group (respectively 417.08±58.12 Ω vs. 476.94±51.29 Ω p=0.006 and 41.33±8.23 Ω vs. 50.61±7.98 Ω p=0.004). Instead, patients in the P-PVD group reported higher values of TBW and ECW than C-PVD group (respectively 44.13±7.57 L vs. 37.96±6.27 L p=0.021 and 21.03±4.06 L vs. 17.24±2.63 L p=0.004). CONCLUSIONS In the present study, we reported a significant correlation between vitreous pathology and anthropometric and BIA measurements.

Abstract
OBJECTIVE Hypertensive retinopathy (HR) is the most common ocular manifestation of systemic arterial hypertension. This paper aims to summarize the current knowledge of HR, reviewing its classical features, such as epidemiology, pathophysiology, clinical manifestations, classifications, management and the most significant systemic correlations. We also provide an update on the latest advances in new technologies focusing on novel instrumental classifications. MATERIALS AND METHODS A literature search was performed to identify articles regarding HR listed in Embase, PubMed, Medline (Ovid) and Scopus database up to 1 December 2021. The reference lists of the analyzed articles were also considered a source of literature information. The following keywords were used in various combinations: hypertensive retinopathy, hypertension and eye, hypertensive retinopathy and systemic correlations, optical coherence tomography (OCT) and hypertensive retinopathy, optical coherence tomography angiography (OCTA) and hypertensive retinopathy, adaptive optics (AO) and hypertensive retinopathy. The authors analyzed all English articles found using the aforementioned keywords. All the publications were thoroughly reviewed to create a detailed overview of this issue. RESULTS HR signs have a significative association with cardiovascular, cerebrovascular and other systemic diseases. Patients with arteriosclerotic changes and, at the same time, severe HR, are at increased risk for coronary disease, peripheral vascular disease, stroke and dementia. HR is even now diagnosed and classified by its clinical appearance on a fundoscopic exam that is limited by interobserver variability. New technologies, like OCT, OCTA, AO and artificial intelligence may be used to develop a new instrumental classification that could become an objective and quantitative method for the evaluation of this disease. They could be useful to evaluate the subclinical retinal microvascular changes due to hypertension that may reflect the involvement of other vital organs. CONCLUSIONS The eye is the only organ in the human body where changes in the blood vessels due to systemic hypertension can be studied in vivo. All doctors should be familiar with this disease because it has been largely demonstrated that signs of HR are correlated to patient's health and mortality. Researchers should develop a new common, standardized, and objective method to assess hypertensive retinal changes; new technologies may have a significant role in this field. This review takes most of the literature published so far, including the OCTA studies in order to stimulate new points of reference to standardize parameters and new diagnostic markers of this disease.

Abstract
Patients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.

Abstract
OBJECTIVE Sarcopenic obesity (OS) is a multifactorial condition characterized by the simultaneous presences of sarcopenia and obesity. The prevalence of OS is increasing in adults over 65 years of age; people with OS present greater health risks than people who are only sarcopenic or obese. Therefore, the study of OS and the search for effective treatment are important due to the constant increase of the elderly population. MATERIALS AND METHODS This review discusses the etiology and evolutionary mechanisms of OS while exploring its molecular, metabolic, oxidative, inflammatory, hormonal, and nutritional stresses. Studies have tried to unravel the causes related to the onset of sarcopenia, which is responsible for the decrease of muscle mass and strength in elderly subjects. The diagnostic criteria and the methods of evaluation of OS are described in these research studies, although there is no univocal definition for these parameters. The most studied treatments in OS are illustrated and highlight how the physical activity performed through both aerobic and resistance exercises, as well as a correct nutritional treatment, prove to be the most effective interventions in the regression of the pathology and in the improvement of physical function. RESULTS New therapies for OS are hypothesized that will open the way to other possible types of intervention in the future. CONCLUSIONS The deficiency of muscle mass in obese elderly subjects will be one of the health challenges of the future to reduce the risk of chronic diseases.

Abstract
Polarization sensitive second harmonic generation (pSHG) microscopy has been used previously to characterize the structure of collagen fibers in corneal samples. Due to the typical organization of the corneal stroma, the information that pSHG provides may be misleading in points where two different collagen fiber bundles orient along different direction crossings. Here, a simulation that illustrates the problem is presented, along with a novel method that is capable of identifying these crossing points. These results can be used to improve the evaluation of corneal collagen structure, and it has been applied to analyze pSHG data acquired from healthy and keratoconic human corneal samples.

Abstract
The treatment of human leishmaniasis is currently based on few compounds that are highly toxic, expensive and have a high rate of treatment failure. A number of recent studies on new drugs focuses on natural or semi-synthetic compounds. Among them, the endoperoxide artemisinin, extracted from Artemisia annua, and some of its derivatives have shown leishmanicidal activity. In the present work, a series of structurally simple, fully synthetic 1,2-dioxanes were evaluated for in vitro antileishmanial activity against promastigotes of Leishmania donovani; the cytotoxicity for mammalian cells was also assessed. The six most promising compounds in terms of activity and selectivity were further investigated for their antileishmanial activity on the promastigote forms of L. tropica, L. major and L. infantum and against L. donovani amastigotes. The good performance in terms of potency and selectivity makes these six hits promising candidates for a preliminary lead optimization as antileishmanial agents.

Abstract
New enantiomerically pure 1,2,4-trioxepanes 10a,b/11a,b were synthesized from D-glucose. Their conformational behavior was studied by low-temperature NMR and substantiated by DFT calculations. On evaluation of in vitro antimalarial activity, the adamantyl derivative 11b showed IC50 values in the low micromolar range, particularly against the W2 chloroquine-resistant Plasmodium falciparum strain (IC50 = 0.15 ± 0.12 μM).

Abstract
We investigated the early effects of whole body vibration (WBV) added to hypocaloric diet on insulin-resistance and other parameters associated with glucose regulation in sedentary obese individuals. We randomly assigned 34 patients to WBV plus hypocaloric diet (WBV group) or diet alone (CON group) for 8 weeks. Fasting and post-load glucose, insulin, lipids, C-reactive protein, tumor necrosis factor-α, leptin, adiponectin were assessed. Insulin sensitivity index (ISI) was derived from oral-glucose-tolerance test. Body composition was evaluated with dual-energy X-ray absorptiometry. Both groups lost approximately 5% of weight, with greater reduction of body fat in WBV than in CON (-7.1±1.2 Kg vs. -5.3±1.0 Kg, p=0.003). Percent variation of ISI was more pronounced in WBV than in CON group (+35±4% vs. + 22±5%, p=0.002), accompanied by slight improvement in post-load glucose (-1.07±0.02 vs. - 0.12±0.01 mmol/l, p=0.031) but without changes in fasting levels. Adiponectin significantly increased in WBV group compared with CON (p=0.021 for comparison) whereas no differences in leptin and inflammatory markers were observed. In middle-aged sedentary obese subjects, WBV added to hypocaloric diet for 8 weeks improved body composition, insulin-resistance, glucose regulation and adiponectin levels to a greater extent compared with diet alone. Efficacy and feasibility of this approach in the long term need to be ascertained.

Abstract
Purpose: To evaluate the position stability of a phakic intraocular lens (Cachet pIOL; Alcon, Laboratories, Inc., Fort Worth, TX) in the anterior chamber (AC) during a 6-months follow-up. Methods: Thirty eyes of 16 subjects underwent a Cachet pIOL implantation for the correction of high myopia from -6.50 to -16.00 D with plano targeted refraction. The position stability of the Cachet pIOL was evaluated using an Anterior Segment-OCT (AS-OCT, Carl Zeiss AG, Oberkochen, Germany) at 1- and 6-months postoperatively. Three measurements have been taken into account: 1) the minimum distance between the anterior surface of the Cachet pIOL optic disk and the central corneal endothelium; 2) the minimum distance between the optic disk’s edges of the pIOL and the endothelium; 3) the minimum distance between the posterior surface of the pIOL optic disk and the anterior surface of the crystalline lens. The endothelial cell density (ECD) was also recorded. Results: No statistically significant changes of the Cachet pIOL position in the AC were found during follow-up. The average changes were ≤0.1 mm between 1- and 6-months postoperatively (P>0.05). At the end of follow-up, The mean ECD loss was 0.7 % (from 2794 ± 337 cell/mm2 to 2776 ± 388 cell/mm2; P>0.05). Conclusion: A high position stability of the Cachet pIOL in the anterior chamber was shown during a 6-months follow-up.

Abstract
BACKGROUND Cutaneous carcinomas are tumors with a potential occupational etiology due to exposure to established carcinogens such as polycyclic aromatic hydrocarbons (PAH), ionizing radiation, ultraviolet (UV) radiation and arsenic. The occupational origin of such neoplasms is hugely underestimated in Italy. OBJECTIVES To asses the proportion of Squamous Cell Carcinomas (SCC) cases with a previous occupational exposure to carcinogens. METHODS We systematically evaluated occupational exposure in a series of consecutive cases, discharged in the period 2010-11 from the Dermatology Unit of Varese Hospital, Italy, with a histological diagnosis of SCC. Through a structured telephone interview we identified patients with a potential exposure to skin carcinogens. As a second-level step, an extensive evaluation by an occupational physician was performed to assess the occupational etiology in those selected cases. RESULTS 105 patients were identified (65 men). 15 male cases out of a total of 85 patients who did the telephone interview, revealed a potential occupational exposure; 7 cases were confirmed as occupational cancers after second-level evaluation (proportion of male occupational cases = 13.2%). UV radiation and PAH were recognized as major causal agents. Applying those results to the national incidence data, we estimated a number of 700 annual occupational cases, 100-fold more than the cases currently evaluated by the Italian National Workers Compensation Authority. CONCLUSIONS Our results revealed that occupational SCC is still at present a substantially "lost disease" in Italy. Greater attention and enhanced collaboration between specialists is thus needed to overcome this tendency.

Abstract
Trace element contents in specimens of hair collected from 137 children aged 11-13 years old, living in Palermo (Sicily, Italy) were determined by ICP-MS. This work reports analytical data for the following 19 elements: Al, As, Ba, Cd, Co, Cr, Cu, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sr, U, V and Zn. The most abundant chemical elements were zinc and copper (Zn > Cu), with concentrations exceeding 10 μg/g (Zn = 189.2 μg/g; Cu = 22.9 μg/g). Other elements with concentrations greater than 1 μg/g were, in order of abundance, Al>Sr>Ba>Pb. The remaining elements were all below 1 μg/g. The average elemental concentrations in hair were statistically compared by Kolmogorov-Smirnov's test taking children's gender into account. Al, Ba, Cr, Li, Rb, Sb, Sr, V and Zn were statistically different according to gender, with significance p < 0.001. This study thus confirms the need for hair analysis to differentiate female data from those of males. IUPAC coverage intervals and coverage uncertainties for trace elements in the analysed hair samples are also reported.

Abstract
OBJECTIVES Perceptions of menstruation vary according to culture and religion. This study addresses attitudes of Italian women towards changes in menstrual frequency induced by oral contraceptives (OCs) administered in an extended regimen. METHODS Three-hundred-and-fifty healthy women of reproductive age were enrolled in three test areas in Italy. Participants completed a standardized questionnaire. One-hundred-and-ten men, aged 21-54 years, accompanying their partners to the gynaecological consultation were also given a questionnaire to get to know their opinion about the extended use of OCs by their partner. RESULTS Only 32% of Italian women prefer to bleed monthly. The preferred frequencies in all age groups were 3-monthly (23.7%) or never (26%). Of the OC-users, 57.2% preferred to bleed less than once a month: 26% wished to bleed every 3 months, and 21.2% once a year. Among men, 58.1% considered an extended OC regimen to be acceptable. CONCLUSIONS About 60% of Italian women with spontaneous or OC-driven cycles prefer to bleed less than monthly. This fact should be kept in mind by physicians when prescribing OCs.

Abstract
7571 Background: Doxorubicin, fludarabine and rituximab are all considered active drugs in the treatment of follicular lymphoma (FL). Howevere, the best induction regimen is still matter of debate. In 2003 the GISL started a phase II trial to assess efficacy and tolerability of a combination of bleomycin, adriamycin, ciclophosphamide, vincristine and prednisone (BACOP) followed by fludarabine and rituximab (FR). Methods: To be included in the study pts should have: histologically confirmed diagnosis of FL, stage II-IV disease, age 18–70, active disease. Pts were assessed for t(14:18) by PCR on bone marrow at diagnosis and at time of response assessment. Treatment consisted in three courses of BACOP followed by 4 courses of FR for pts in partial remission (PR) or complete remission with persistent t(14:18) positivity (CRM+). Pts achieving molecular complete remission (CRM-) stopped therapy after BACOP. The main endpoints of the study were overall response rate (CR+PR) (ORR) and failure free survival (FFS). A final accrual of 60 assessable pts was planned, however a faster accrual than expected allowed to enrol 91 pts between May 2003 and Dec 2005. Results: At time of present analysis 61 pts were valuable for final response: Median age was 56 yrs (25–70), male gender 56%, 18% with systemic symptoms, 88% in stage III-IV disease, 13% had elevated LDH and 21% bulky disease. Molecular marker was present in 30 out of 57 pts. 19 pts achieved a CR after three courses of BACOP; four of them, being in CRM- stopped therapy. 28 pts achieved CR with four additional courses of FR. At the end of treatment CR and ORR were 77% and 90% respectively; relatively to pts with molecular marker at diagnosis CRM- was 60%. Toxicity data are available for 57 patients: grade III/IV anemia and neutropenia were observed in two (3%) and 18 (32%) cases respectively; severe infections occurred in two cases, both bacterial pneumonia. After a median follow-up of 17 months (0.5–31) 12 events were observed: Major toxicity, four; non responders, two; relapse, six. Conclusions: BACOP/FR is a feasible and safe regimen for the treatment of patients with FL with promising efficacy. More mature follow-up is required to confirm these preliminary results. No significant financial relationships to disclose.

Abstract
BACKGROUND It is still unclear the actual contribute of dose intensity (DI), dose size (DS) and dose density (DD) in the conventional chemotherapy of large, B-cell non-Hodgkin lymphomas. METHODS A prospective, randomized trial compared the cyclic schedule of ProMECE-CytaBOM chemotherapy (cyc-PC, 6 cycles) with a modified version of it, which administered the same drugs sequentially (seq-PC), with the same planned cumulative DI and an 83% DD, within the same time frame (113 days), but with three times higher DS of all the drugs except vincristine. RESULTS Fifty-six patients received cyc-PC and 52 seq-PC. The actual mean cumulative DI was 0.79 +/- 0.15 with cyc-PC, 0.78 +/- 0.17 with seq-PC. Response was complete in 59% and 52%, partial in 20% and 21%, null in 5% and 6%, respectively. There were four toxic deaths (two per arm). Relapses occurred in 36% and 37%, respectively. Toxicity was similar in both arms. Overall, failure-free, progression-free and disease-free survival (median follow-up: 54 months) were statistically indifferent. CONCLUSIONS The very similar DI actually delivered in both arm seems to be the main common determinant of the indifferent results recorded. Increasing DS--at least within the limits clinically attainable without stem cell rescue--does not improve results.

Abstract
A singularly long-surviving (15 years) disease-free case of a stage II adenosquamous carcinoma of the larynx is described. A review of the literature reveals that prognosis of this aggressive malignant neoplasm is poor (mean 2-3 years free of disease) on account of local recurrences, early cervical lymph node metastasis and distant dissemination. This long survival rate emphasises the importance of early radical surgical treatment and the choice of total laryngectomy with neck dissection in stage II laryngeal neoplasm.

Abstract
Aims of this study were to investigate menarcheal age (MA) and menarcheal determinants in 25 girls with cystic fibrosis (CF) and to compare their MA with their respective mothers'. Patients' MA (13.3 +/- 1.1 yr) was on average significantly higher (p<0.0005) than that of the respective mothers (12.2 +/- 1.0 yr) and positively related to it (r=0.055, p<0.005). Six girls experienced menarche after 14.2 yr, ie after the uppest limit of their mothers' MA range. The only parameter which significantly differentiated these 6 patients from the remaining 19 cases was body mass percentile (BMP). Moreover, in the entire patient series a negative correlation was found between MA and BMP. None of the other clinical parameters correlated significantly with MA. No differences in terms of MA were detected in the subgroups of patients with a different glucose tolerance (GT) status and the 12 girls with a pathological GT were not older at menarche than those with normal GT. No correlations were found between either glucose or insulin areas during oral GT test and MA. In the subgroups of patients with a different genotype menarche occurred at a similar age, irrespectively of their genotype. On the basis of our findings we conclude that: a) a menarcheal delay of approximately 1 yr exists between CF girls and their mothers; b) menarcheal delay in CF is not related to either genotype or disease severity or glycometabolic status; c) the only two factors which are able to affect MA in CF are maternal MA and nutritional status.

Abstract
BACKGROUND/AIMS Very few studies have been performed on the long-term clinical advantages of neonatal screening programs for cystic fibrosis (CF) and these have been inconclusive. This is a preliminary report of two observational cohort studies on this subject. METHODS In the first study, CF patients born between 1973 and 1981 in northeastern Italy were split into 4 groups according to the modality of diagnosis: screening by meconium test (58 patients); meconium ileus (45 patients); symptoms and pancreatic insufficiency (PI; 75 patients), or symptoms and pancreatic sufficiency (PS; 19 patients). The patients were followed for up to 26 years by three CF centers sharing common treatment protocols. In the second study, two cohorts of CF patients born between 1983 and 1992 were compared. Patients from one cohort (126 patients) were born in the Veneto region, where a neonatal screening program had been established based on immunoreactive trypsinogen. Patients from the other cohort (152 patients) were born in Sicily, where an intensive program of early diagnosis by symptoms was implemented. The cohorts were comparable for CF incidence, CFTR genotypes, gender proportion and common treatment protocols. Statistical analyses were performed by Kaplan-Meier survival curves, a Cox proportional hazard model for survival and cross-sectional comparisons by 2-year periods for weight z score, height z score and body mass index. RESULTS In the first study, the patients detected by newborn screening (PI) showed better survival and nutritional status compared to patients diagnosed through meconium ileus or symptom presentation with PI. PS patients diagnosed by symptoms showed the best outcome, but most of them had a mild genotype. In the second study, the Veneto cohort showed better outcome with regard to survival and nutritional status over 16 years of follow-up. CONCLUSIONS Observational cohort studies cannot give definitive evidence of the clinical benefit of neonatal CF screening; however, data have been accumulated which strongly suggest a better clinical outcome for CF patients born in an area where a screening program is performed.

Abstract
OBJECTIVES This study investigated the prognostic value of left ventricular (LV) mass at echocardiography in uncomplicated subjects with essential hypertension. BACKGROUND Only a few single-center studies support the prognostic value of LV mass in uncomplicated hypertension. METHODS The MAssa Ventricolare sinistra nell'Ipertensione study was a multicenter (45 centers) prospective study. The prespecified aim was to explore the prognostic value of LV mass in hypertension. Admission criteria included essential hypertension, no previous cardiovascular events, and age > or =50. There was central reading of echocardiographic tracings. Treatment was tailored to the single subject. RESULTS Overall, 1,033 subjects (396 men) were followed for 0 to 4 years (median, 3 years). Mean age at entry was 60 years, and systolic/diastolic blood pressure was 154/92 mm Hg. The rate of cardiovascular events (x100 patient-years) was 1.3 in the group with normal LV mass and 3.2 in the group (28.5% of total sample) with LV mass > or =125 g/body surface area (p = 0.005). After adjustment for age (p < 0.01), diabetes (p < 0.01), cigarette smoking (p < 0.01) and serum creatinine (p = 0.03), LV hypertrophy was associated with an increased risk of events (RR [relative risk] 2.08; 95% CI [confidence interval]: 1.22 to 3.57). For each 39 g/m(2) (1 SD) increase in LV mass there was an independent 40% rise in the risk of major cardiovascular events (95% CI: 14 to 72; p = 0.0013). CONCLUSIONS Our findings show a strong, continuous and independent relationship of LV mass to subsequent cardiovascular morbidity. This is the first study to extend such demonstration to a large nationwide multicenter sample of uncomplicated subjects with essential hypertension.

Abstract
A new precursor of a formal 1-hydroxy allyl anion is represented by 3-bromo-1-acetoxy-1-propene, which is synthesized by the ZnCl(2)-catalyzed addition of acetyl bromide to propenal. 3-Bromo-1-acetoxy-1-propene reacts with indium powder in THF to give the corresponding 3-acetoxylated ally indium complex, which regioselectively adds to aldehydes, affording monoprotected 1-en-3,4-diols. Diastereoselectivity mainly depends on the nature of the aldehyde; saturated aldehydes afford anti adducts, whereas the alpha,beta-unsaturated aldehydes preferentially lead to the syn isomers. Reaction: see text.

Abstract
BACKGROUND Ifosfamide (IFO) and cisplatin (CDDP) are active drugs in the treatment of patients with squamous cell carcinoma (SCC) of the head and neck. 13-Cis retinoic acid (RA), along with its antiproliferative and differentiating activity on SCC cell lines, has immunomodulatory and chemopreventive effects. The objective of the current Phase I-II study was to evaluate the combination of CDDP, IFO, and RA in patients with advanced or recurrent SCC of the head and neck. METHODS Patients with measurable recurrent, metastatic, or locally advanced SCC of the head and neck were eligible. Patients received a fixed dose of 20 mg/m(2) CDDP, and IFO was administered with sodium mercaptoethanesolfonate in three-dose increments (1000 mg/m(2), 1200 mg/m(2), and 1500 mg/m(2)) up to dose limiting toxicity. Both drugs were given for 5 consecutive days every 3 weeks. RA (0.5 mg/kg) was given orally for 5 days per week. RESULTS Fifty-two patients either with locoregional recurrence or distant metastases (50%) or with locally advanced SCC of the head and neck beyond surgery or radiation therapy (50%) were entered into the trial. Fifteen patients were enrolled in the Phase I study, during which the maximum tolerated dose of IFO was 1500 mg/m(2). In the Phase II study (CDDP 20 mg/m(2) and IFO 1200 mg/m(2)), the response rate was 72% (95% confidence interval, 57-83%). After a median follow-up of 23 months, the median time to disease progression was 10.4 months (range, 2.9-47.2+ months), and the median overall survival was 12.95 months (range, 1.7-47.2+ months). Two patients were converted from a partial response to a complete response with RA. Toxicity was relatively well tolerated and caused no deaths. Grade 3-4 neutropenia was observed in 16 patients, and Grade 2-3 diarrhea toxicity occurred in 9 patients. CONCLUSIONS The dose and schedule for the combination of CDDP, IFO, and RA that were used in this study are feasible and active in the treatment of patients with SCC of the head and neck, with durable responses and a relatively well tolerated toxicity.

Abstract
It is well known that hypertension is a highly prevalent condition in the population, carries a significant risk of adverse cardiovascular events and is therapeutically difficult to control. These factors render it "a major unsolved - but soluble - mass public health problem". One of the present-day aspects of the complexity of managing patients with high blood pressure (BP) derives from clinical and epidemiological data that have emerged over the past 10 years: the growing importance of the clinical significance of systolic and pulse BP. The pathophysiological basis of these data is based, on the one hand, on a better articulated definition of the components of BP, and on the other, on precise information concerning age-related modifications. The common definition of BP does not take into account pressure fluctuations occurring during the cardiac cycle; in fact, systolic and diastolic BP denote the extreme values of continuous variations in differential pressure. Diastolic BP reflects, to a greater extent, the trend of arterial resistances and mean BP (usually calculated as diastolic BP plus one third of the differential BP, and considered the "stable component" of the arterial sphygmogram) and has long been used as a diagnostic and therapeutic target. Systolic BP is more closely linked to variations in pulse BP (given from the difference between systolic and diastolic BP and considered the "dynamic component" of the arterial sphygmogram) and is produced by a group of factors including left ventricular ejection and the reflection of the sphygmic wave. As age increases, the walls of the aorta and the large elastic arteries progressively harden due to senile degenerative phenomena and the loss of elasticity as well as the progressive diffusion of atherosdclerotic lesions. This leads to the reduced capacity of the arterial wall to distend during the systole with a consequent increase in both systolic and pulse BP. These pathophysiological data have important clinical and prognostic implications and account for the possible diversity of significance to attribute to systolic, diastolic, mean and pulse BP, factors which, in their entirety, can represent an element, albeit partial, of resolvability of problems in managing hypertension. In fact, possibilities of diversification in the stratification of risk of the hypertensive patients may be considered on a pathophysiological basis, with the prospect of better aimed therapeutic interventions. On the whole, it appears that the clinical significance to attribute to pulse BP should be considered not as an alternative to that of systolic and diastolic BP, but rather in complementary terms, with age kept in careful consideration. In practice, by simplifying to a maximum the state of present knowledge, the values of systolic, diastolic, mean and pulse BP are all important in subjects under 60 years old. This indicates that the clinical significance to attribute to diastolic hypertension in young or middle-aged patients, which have been so accurately described by well-known meta-analyses, is not presently under discussion. What seems to change, with respect to the past, is the importance that should be attributed to the systolic and pulse BP in subjects of all ages and in particular to pulse BP in subjects over 60 years old: in these persons, the increase in pulse BP summarizes and integrates the adverse prognostic value of an elevated systolic BP and a low diastolic BP. It should be clearly understood that, in subjects over 60 years old, a high systolic BP and a low diastolic BP mean rigidity of the wall of the aorta and of the main elastic arteries; in these subjects, the isolated increase in diastolic BP, usually easily controllable by antihypertensive treatment, should not cause excessive clinical concern; instead, an increase in systolic BP - even if isolated - and, above all, an increase in pulse BP, should cause greater preoccupation, inasmuch as they are signs of consistent serious structural lesions. In other words, a 60-year-old subject with 150/90 mmHg would have a lesser risk of cardiovascular events, particularly cardiological events, than a contemporary with equal risk factors who has 150/50 mmHg. A large number of clinical studies suggest that an increase in pulse BP seems to predict cardiac ischemic events to a greater extent than the cerebrovascular events, which seem to be predicted to a greater extent by the mean BP. On the therapeutic level, the reference datum is represented by the unequivocal demonstration, furnished by wide scale interventional studies, that in hypertensive patients adequate pharmacological control of both the diastolic and systolic BP, particularly in the elderly, significantly reduces adverse consequences linked to the progression of atherosclerotic disease in the heart, brain and kidney. A degree of complexity is represented by the modest percent of patients in treatment who have BP values < 140/90 mmHg. Only a series of ad hoc studies will enable us to know when and if this negative situation can be resolved, even partially, by the clinical application of new knowledge in the pathophysiological field. From this point of view, it should be kept in mind that ACE-inhibitors, diuretics, dihydropyridinic calcium antagonists and vasopeptidase inhibitors seem to be more effective than beta-blockers in terms of preferential reduction of pulse BP. The contents of the reports that make up the Symposium constitute a valid base of knowledge and represent a concrete stimulus for research initiatives, which in the spirit of "operativeness" of the Area Prevenzione of the Italian Association of Hospital Cardiologists, follow the objective of bringing together scientific and managerial needs.

Abstract
A short synthesis of 1,4-dideoxy-1,4-imino-L-arabinitol (LAB1) (4) and of 1,4-dideoxy-1,4-imino-D-galactitol (5), two azasugars active as enzymatic inhibitors, is reported. The key reaction is the addition of vinylmagnesium chloride to (3S,4S)-3,4-bis(benzyloxy)-3,4-dihydro-2H-pyrrole 1-oxide (3), a nitrone easily available from L-tartaric acid. Unexpectedly, the reaction affords the corresponding (2S,3S,4S)-1-hydroxy-2-ethenyl-3,4-bis(benzyloxy)pyrrolidine (9) in very good yield and in 93/7 diastereomeric ratio (dr) independently of the reaction temperature, thus representing a unique case of entropy-controlled reaction in a 100 K interval (from +20 degrees C to -80 degrees C). The trans intermediate 9 is converted in two steps (reduction, N-protection) into the common intermediate (2S,3S,4S)-1-(benzyloxycarbonyl)-3,4-bis(benzyloxy)-2-ethenylpyrrolidine (11). Double bond oxidation followed by reductive debenzylation opens a route to the target pyrrolidine azasugars 4 and 5.

Abstract
The hydroboration of propargyl bromide with dialkylboranes takes place regioselectively to give 3-bromoprop-1-en-1-yl dialkylboranes 13 which, upon quaternization with bromide ion, undergo a series of transformations into a number of allylic boron species. By a suitable choice of the experimental conditions it is possible to trap the reaction intermediates with aldehydes and to steer the process toward either the synthesis of (Z)-1-bromoalk-1-en-4-ols 6 or anti-homoallylic alcohols 8. Two one-pot three-component processes were developed based on a sequence of four reactions; preparation of dialkylborane and hydroboration of propargyl bromide are the first steps. Then, quaternization with TEBABr may be carried out either in the presence of the aldehyde when (Z)-1-bromoalk-1-en-4-ols 6 are requested, or in the absence of the aldehyde in order to allow the formation of gamma-substituted allyl borane 18 which, successively, adds to the aldehyde affording anti-homoallylic alcohols 8.

Abstract
BACKGROUND The goal of this study was to evaluate whether endothelial dysfunction associated with acute estrogen deprivation is caused by an alteration in the L-arginine-nitric oxide (NO) pathway and oxidative stress. Methods and Results-In 26 healthy women (age, 45.7+/-5.4 years) and 18 fertile women with leiomyoma (age, 44.5+/-5.1 years), we studied forearm blood flow (strain-gauge plethysmography) changes induced by intrabrachial acetylcholine (0. 15, 0.45, 1.5, 4.5, or 15 microgram. 100 mL(-1). min(-1)) or sodium nitroprusside (1, 2, or 4 microgram. 100 mL(-1). min(-1)), an endothelium-dependent or -independent vasodilator, respectively. The NO pathway was evaluated by repeating acetylcholine during L-arginine (200 microgram. 100 mL(-1). min(-1); 13 control subjects and 9 patients) or N(G)-monomethyl-L-arginine (L-NMMA; 100 microgram. 100 mL(-1). min(-1); 13 control subjects and 9 patients); production of cyclooxygenase-derived vasoconstrictors was assessed by repeating acetylcholine during indomethacin (50 microgram. 100 mL(-1). min(-1); 13 control subjects and 9 patients) or vitamin C (8 mg. 100 mL(-1). min(-1); 13 control subjects and 9 patients). Patients repeated the study within 1 month after ovariectomy and again after 3 months of estrogen replacement therapy (ERT; 17 beta-estradiol TTS, 50 microgram/d). Basally, vasodilation to acetylcholine was potentiated and inhibited by L-arginine and L-NMMA, respectively (P<0.05), but was unaffected by indomethacin or vitamin C. After ovariectomy, the modulating effect of L-arginine and L-NMMA disappeared, whereas indomethacin and vitamin C potentiated the response to acetylcholine (P<0.05). ERT restored L-arginine and L-NMMA effects on vasodilation to acetylcholine but prevented the potentiation caused by indomethacin or vitamin C. Response to sodium nitroprusside was unaffected by either ovariectomy or ERT. CONCLUSIONS Endothelial dysfunction secondary to acute endogenous estrogen deprivation is caused by reduced NO availability. Cyclooxygenase-dependent production of oxidative stress could be responsible for this alteration.

Abstract
We report one case of leiomyosarcoma (LMS) of the larynx occurring in a patient with a history of immunosuppressive therapy, and offer a critical review of the literature. Epstein-Barr virus (EBV) genome was not identified in the neoplastic cells. The patient was treated with endoscopic resection and post-operative radiotherapy. Lung metastasis and thyroid infiltration became evident 14 months following treatment despite the absence of laryngeal recurrence. Progressive decline occurred and the patient died 15 months after diagnosis.

Abstract
Cytogenetic analysis performed on 73 sporadic basal cell carcinomas (BCCs) and three squamous cell carcinomas (SCCs) showed different findings in direct preparations (24 hours) and in short-term cell cultures. Except for loss of the Y chromosome, not one of the other clonal (+6, +16, add(2)(q37), del(3)(q13), add(1)(p31), and near triploidy) or sporadic changes found in direct preparations was found in cell cultures and vice versa. Clonal trisomy 6 found in two BCC direct preparations and demonstrated by interphase fluorescence in situ hybridization in 8 other cases seems to be a nonrandom change in basal cell carcinoma. Immunohistochemistry showed that the cell type investigated was different in the two methods of analysis used: epithelial in direct preparations and fibroblastic in cell cultures. Thus, the results obtained in direct preparations indicate the BCC or SCC epithelial karyotype, whereas the aberrations found in cell cultures indicate the presence of chromosome instability in the fibroblastic stroma. The apparent lack of correspondence between direct and indirect preparations and the presence of clonal chromosome changes in both epithelial and stromal cells suggest tumor cell heterogeneity of BCC. The fibroblastic stroma seems to be implicated in the neoplastic process. This is not evident in SCC, in which clonal changes are present only in direct preparations. The chromosomal distribution of the breakpoints involved in structural changes in direct and cell culture preparations is random; together with those reported in the literature, the breakpoints found in BCC cultures show, however, a cluster to 1p36, 3q13, 9q22, 14p11, 15p11, and Xp11 bands. We did not find any significant correlations between BCC cytogenetic results and the clinical data (site, age, sex, recurrence). The incidence of cases of BCC (38%) and of SCC (100%) showing clonal chromosome changes agree with their benign and malignant nature, respectively. Finally, a significantly high incidence of constitutional inv(9) and dup(9)(q11q21) was found in the group of patients with BCC.

Abstract
BACKGROUND Suppression of tumor growth by thrombospondin-1 (TSP-1) has been associated with its ability to inhibit neovascularization. The antiangiogenic activity of TSP-1, as defined by cornea pocket assays, was previously mapped to the amino-terminal portion of the protein within the procollagen region and the type 1 repeats. METHODS AND RESULTS We evaluated the specificity and efficacy of different regions of TSP-1 using recombinant fragments of the protein on chorioallantoic membrane (CAM) angiogenesis and endothelial cell proliferation assays. In both assays, fragments containing the second and third type 1 repeats but not the procollagen region inhibited angiogenesis and endothelial cell proliferation. To further define the sequences responsible for the angiostatic effect of TSP-1, we used synthetic peptides. The CAM assay defined 2 sequences that independently suppressed angiogenesis. The amino-terminal end of the type 1 repeats showed higher potency for inhibiting angiogenesis driven by basic fibroblast growth factor (FGF-2), whereas the second region equally blocked angiogenesis driven by either FGF-2 or vascular endothelial growth factor (VEGF). Modifications of the active peptides revealed the specific amino acids required for the inhibitory response. One sequence included the conserved tryptophan residues in the amino-terminal end of the second and third type 1 repeats, and the other involved the amino acids that follow the CSVTCG sequence in the carboxy-terminus of these repeats. Both inhibition in the CAM assay and inhibition of breast tumor xenograft growth in nude mice were independent of the TGF-beta-activating sequence located in the second type 1 repeat. CONCLUSIONS These results indicate that the type 1 repeats of TSP-1 contain 2 subdomains that may independently inhibit neovascularization. They also identify 2 independent pathways by which TSP-1 can block FGF-2 and VEGF angiogenic signals on endothelial cells.

Abstract
BACKGROUND The aim of this clinical trial was to assess the efficacy and safety of calcipotriol cream associated with oral etretinate compared with etretinate alone in the treatment of moderate-severe psoriasis. METHODS This controlled multicenter trial, within patients (hemiparts), enrolled 86 in- or out-patients (62 males, 24 females), mean (+/-SD) age 57.1 +/- 14.2 years, with psoriasis vulgaris on both sides of the body, and mean (+/-SE) baseline PASI score (Psoriasis Area and Severity Index) 30.7 +/- 0.9. All patients took oral etretinate 50 mg/day and applied calcipotriol cream (50 microg/g) on one half of their body twice a day. Treatment was continued for 9 weeks, and patients were seen every 3 weeks. RESULTS At the end of the first 3 weeks the PASI score indicated a significant clinical difference between the two sides of the body (P < 0.001, ANOVA), with a reduction of 50.7% in the score for the calcipotriol-treated half, compared with a 39% reduction for the untreated half. By the 9th week of treatment the PASI score was 81.4% lower on the treated half, and 70.3% on the untreated side (P < 0.001, ANOVA). CONCLUSIONS These findings suggest that patients with moderate-severe psoriasis might benefit from treatment with etretinate plus calcipotriol, with the aim of achieving a faster response and an overall smaller total dose of etretinate.

Abstract
We have studied two related proteins that contain a repeated amino acid motif homologous to the anti-angiogenic type 1 repeats of thrombospondin-1 (TSP1). Complete sequence analysis revealed no other similarities with TSP1, but identified unique signal sequences, as well as metalloprotease and disintegrin-like domains in the NH(2) termini. We named these proteins METH-1 and METH-2 due to the novel combination of metalloprotease and thrombospondin domains. Overall amino acid sequence identity between METH-1 and METH-2 is 51. 7%, yet transcript distribution revealed non-overlapping patterns of expression in tissues and cultured cell lines. To characterize these proteins functionally, we isolated full-length cDNAs, produced recombinant protein, and generated antisera to the recombinant proteins. Both METH-1 and METH-2 represent single copy genes, which encode secreted and proteolytically processed proteins. METH proteins suppressed fibroblast growth factor-2-induced vascularization in the cornea pocket assay and inhibited vascular endothelial growth factor-induced angiogenesis in the chorioallantoic membrane assay. Suppression of vessel growth in both assays was considerably greater than that mediated by either thrombospondin-1 or endostatin on a molar basis. Consistent with an endothelial specific response, METH-1 and METH-2 were shown to inhibit endothelial cell proliferation, but not fibroblast or smooth muscle growth. We propose that METH-1 and METH-2 represent a new family of proteins with metalloprotease, disintegrin, and thrombospondin domains. The distinct distribution of each gene product suggests that each has evolved distinct regulatory mechanisms that potentially allow for fine control of activity during distinct physiological and pathological states.

Abstract
BACKGROUND AND OBJECTIVE Although in recent years anaplastic large-cell lymphoma (ALCL) has emerged as a distinct clinico-pathological entity, a gold standard for treatment has still not been defined. Goals of our histologic, phenotypic and clinical study were to present clinical findings, treatment outcome and survival rates of a small, but highly homogeneously treated, series of patients. DESIGN AND METHODS From April 1991, 36 newly diagnosed adult patients with systemic ALCL CD30+, entered a prospective non-randomized trial in one of the institutions participating in a GISL (Gruppo Italiano per lo studio dei Linfomi) study and were treated with a MOPP/EBV/CAD hybrid scheme. Chemotherapy (CHT) was administered every 28 days, for a total of 6 cycles. After CHT, 19 patients received radiation therapy (RT) to the site of previously involved fields. Kaplan and Meier and log-rank tests were used for statistical analysis. RESULTS The overall complete remission rate was 78%, the partial remission rate was 6%. The overall survival rate at 74 months was 69%. No statistically significant differences in response or survival rates were noted comparing ALCL-HL and -CT subgroups, T+ Null- and B- subtypes, or ALCL-HL and -CT, with different phenotypes. In the analysis of patients with T+ Null phenotype treated with CHT+RT in comparison with B-ALCL patients who had the same treatment, we observed statistically significant differences in the survival rate (p=0.048). No prognostic factors predictive of response or survival were identified. INTERPRETATION AND CONCLUSIONS Our results show that using MOPP/ABV/CAD the results, in terms of remission rate and survival, are similar to those obtained with 3rd generation CHT regimens. The diagnosis of T and Null ALCL is the most important prognostic factor, because it is associated with a very good survival, even in patients with a high prognostic index. Finally, we believe that longer follow-ups are needed to evaluate long-term survival and toxicity with different treatments.

Abstract
Cystic Fibrosis (CF) is a recessive autosomic genetic disease with an incidence in mediterranean countries of about 1:3500 born alive. In Italy the considerable genetic variability makes it difficult to identify all the homozygous subjects and, consequently, to estimate the incidence of the disease in healthy carriers. The disease is evolutive and affects various systems, most of all the respiratory and gastrointestinal systems. Not many years ago, when the clinical definition of CF was first introduced, average survival did not exceed the pediatric age. Nowadays with ever advancing diagnostic and therapeutical techniques many CF patients survive until an adult age. It is therefore necessary to plan adequate health service interventions so as to satisfy as much as possible the needs of both the patients and their families. To this end data collected since 1.1.1988 by the Italian registry for CF (year of birth, sex, region of birth and residence, diagnosis procedures, results of sweat test, pancreatic insufficiency, DNA analysis, status: alive, dead, lost to follow up) of all the patients, diagnosed in the 18 Reference Centres and the 3 local Centres for CF, have proved to be extremely useful. Since the birth of the Registry on 31.12.1997, data relating to 2458 patients alive on 1.1.1988 and 1159 born during the last ten years, for a total of 3617 subjects (1756 females and 1861 males), have been recorded. As already mentioned a considerable increase in life expectancy of CF patients (from 1988 to 1990 the average age of death was 14 years, from 1994 to 1997 it was 19) and a consequent increase in the percentage of adult patients have been observed.

Endostatin is a Mr 20,000 COOH-terminal fragment of collagen XVIII that inhibits the growth of several primary tumors. We report here the cloning and expression of mouse endostatin in both prokaryotic and eukaryotic expression systems. Soluble recombinant protein expressed in yeast (15-20 mg/L) inhibited the proliferation and migration of endothelial cells in response to stimulation by basic fibroblast growth factor. A rabbit polyclonal antibody was raised that showed positive immunoreactivity to the recombinant protein expressed from both systems. Importantly, the biological activity of the mouse recombinant protein could be neutralized by this antiserum in both endothelial proliferation and chorioallantoic membrane assays. Systemic administration of endostatin at 10 mg/kg suppressed the growth of renal cell cancer in a nude mouse model. The inhibition of tumor growth with soluble yeast-produced protein was comparable to that obtained with non-refolded precipitated protein expressed from bacteria. In addition, two closely related COOH-terminal deletion mutants of endostatin were also tested and showed strikingly differing activity. Collectively, these findings demonstrate the expression of a biologically active form of mouse endostatin in yeast, define a role for the molecule in inhibiting endothelial cell migration, extend its antitumor effects to renal cell carcinoma, and provide a formal proof (via the neutralizing antiserum experiments and the mutant data) that endostatin (and not a possible contaminant) acts as an antiangiogenic agent. Finally, the high level expression of mouse endostatin in yeast serves as an endotoxin free, soluble source of protein for fundamental studies on the mechanisms of tumor growth suppression by angiogenesis inhibitors.
