Abstract
BACKGROUND The COVID-19 pandemic has increased the incidence of ventilator-associated pneumonia (VAP) among critically ill patients. However, a comparison of VAP incidence in COVID-19 and non-COVID-19 cohorts, particularly in a context with a high prevalence of multidrug-resistant (MDR) organisms, is lacking. MATERIAL AND METHODS We conducted a single-center, mixed prospective and retrospective cohort study comparing COVID-19 patients admitted to the intensive care unit (ICU) of the "Città della Salute e della Scienza" University Hospital in Turin, Italy, between March 2020 and December 2021 (COVID-19 group), with a historical cohort of ICU patients admitted between June 2016 and March 2018 (NON-COVID-19 group). The primary objective was to define the incidence of VAP in both cohorts. Secondary objectives were to evaluate the microbial cause, resistance patters, risk factors and impact on 28 days, ICU and in-hospital mortality, duration of ICU stay, and duration of hospitalization). RESULTS We found a significantly higher incidence of VAP (51.9% - n = 125) among the 241 COVID-19 patients compared to that observed (31.2% - n = 78) among the 252 NON-COVID-19 patients. The median SOFA score was significantly lower in the COVID-19 group (9, Interquartile range, IQR: 7-11 vs. 10, IQR: 8-13, p < 0.001). The COVID-19 group had a higher prevalence of Gram-positive bacteria-related VAP (30% vs. 9%, p < 0.001), but no significant difference was observed in the prevalence of difficult-to-treat (DTR) or MDR bacteria. ICU and in-hospital mortality in the COVID-19 and NON-COVID-19 groups were 71% and 74%, vs. 33% and 43%, respectively. The presence of COVID-19 was significantly associated with an increased risk of 28-day all-cause hospital mortality (Hazard ratio, HR: 7.95, 95% Confidence Intervals, 95% CI: 3.10-20.36, p < 0.001). Tracheostomy and a shorter duration of mechanical ventilation were protective against 28-day mortality, while dialysis and a high SOFA score were associated with a higher risk of 28-day mortality. CONCLUSION COVID-19 patients with VAP appear to have a significantly higher ICU and in-hospital mortality risk regardless of the presence of MDR and DTR pathogens. Tracheostomy and a shorter duration of mechanical ventilation appear to be associated with better outcomes.

Abstract
Mismatch repair (MMR) testing on all new cases of colorectal cancer (CRC) has customarily been preferably performed on surgical specimens, as more tissue is available; however, new clinical trials for the use of immune checkpoint inhibitors in the neoadjuvant setting require MMR testing on biopsy samples. This study aims at identifying advantages, disadvantages and any potential pitfalls in MMR evaluation on biopsy tissue and how to cope with them. The study is prospective-retrospective, recruiting 141 biopsies (86 proficient (p)MMR and 55 deficient (d)MMR) and 97 paired surgical specimens (48 pMMR; 49 dMMR). In biopsy specimens, a high number of indeterminate stains was observed, in particular for MLH1 (31 cases, 56.4%). The main reasons were a punctate nuclear expression of MLH1, relatively weak MLH1 nuclear expression compared to internal controls, or both (making MLH1 loss difficult to interpret), which was solved by reducing primary incubation times for MLH1. A mean of ≥ 5 biopsies had adequate immunostains, compared to ≤ 3 biopsies in inadequate cases. Conversely, surgical specimens rarely suffered from indeterminate reactions, while weaker staining intensity (p < 0.007) for MLH1 and PMS2 and increased patchiness grade (p < 0.0001) were seen. Central artefacts were almost exclusive to surgical specimens. MMR status classification was possible in 92/97 matched biopsy/resection specimen cases, and all of these were concordant (47 pMMR and 45 dMMR). Evaluation of MMR status on CRC biopsy samples is feasible, if pitfalls in interpretation are known, making laboratory-specific appropriate staining protocols fundamental for high-quality diagnoses.

Abstract
BACKGROUND Combined small-cell lung cancer (C-SCLC) is composed of SCLC admixed with a non-small-cell cancer component. They currently receive the same treatment as SCLC. The recent evidence that SCLC may belong to either of two lineages, neuroendocrine (NE) or non-NE, with different vulnerability to specific cell death pathways such as ferroptosis, opens new therapeutic opportunities also for C-SCLC. MATERIALS AND METHODS Thirteen C-SCLCs, including five with adenocarcinoma (CoADC), five with large-cell neuroendocrine carcinoma (CoLCNEC) and three with squamous cell carcinoma (CoSQC) components, were assessed for alterations in 409 genes and transcriptomic profiling of 20 815 genes. RESULTS All 13 cases harbored TP53 (12 cases) and/or RB1 (7 cases) inactivation, which was accompanied by mutated KRAS in 4 and PTEN in 3 cases. Potentially targetable alterations included two KRAS G12C, two PIK3CA and one EGFR mutations. Comparison of C-SCLC transcriptomes with those of 57 pure histology lung cancers (17 ADCs, 20 SQCs, 11 LCNECs, 9 SCLCs) showed that CoLCNEC and CoADC constituted a standalone group of NE tumors, while CoSQC transcriptional setup was overlapping that of pure SQC. Using transcriptional signatures of NE versus non-NE SCLC as classifier, CoLCNEC was clearly NE while CoSQC was strongly non-NE and CoADC exhibited a heterogeneous phenotype. Similarly, using ferroptosis sensitivity/resistance markers, CoSQC was classified as sensitive (as expected for non-NE), CoLCNEC as resistant (as expected for NE) and CoADC showed a heterogeneous pattern. CONCLUSIONS These data support routine molecular profiling of C-SCLC to search for targetable driver alterations and to precisely classify them according to therapeutically relevant subgroups (e.g. NE versus non-NE).

Abstract
BACKGROUND AND PURPOSE The aim was to assess functional and radiological outcomes after bridging therapy (intravenous thrombolysis plus mechanical thrombectomy) versus direct mechanical thrombectomy (MT) in unknown onset stroke patients. METHODS A cohort study was conducted on prospectively collected data from unknown onset stroke patients who received endovascular procedures at ≤6 h from symptom recognition or awakening time. RESULTS Of the 349 patients with a 10-point Alberta Stroke Program Early Computed Tomography Score (ASPECTS), 248 received bridging and 101 received direct MT. Of the 134 patients with 6-9-point ASPECTS, 123 received bridging and 111 received direct MT. Each patient treated with bridging was propensity score matched with a patient treated with direct MT for age, sex, study period, pre-stroke disability, stroke severity, type of stroke onset, symptom recognition to groin time (or awakening to groin time), ASPECTS and procedure time. In the two matched groups with 10-point ASPECTS (n = 73 vs. n = 73), bridging was associated with higher rates of excellent outcome (46.6% vs. 28.8%; odds ratio 2.302, 95% confidence interval 1.010-5.244) and successful recanalization (83.6% vs. 63%; odds ratio 3.028, 95% confidence interval 1.369-6.693) compared with direct MT; no significant association was found between bridging and direct MT with regard to rate of symptomatic intracerebral hemorrhage (0% vs. 1.4%). In the two matched groups with 6-9-point ASPECTS (n = 45 vs. n = 45), no significant associations were found between bridging and direct MT with regard to rates of excellent functional outcome (44.4% vs. 31.1%), successful recanalization (73.3% vs. 76.5%) and symptomatic intracerebral hemorrhage (0% vs. 0%). CONCLUSIONS Bridging at ≤ 6 h of symptom recognition or awakening time was associated with better functional and radiological outcomes in unknown onset stroke patients with 10-point ASPECTS.

Abstract
Monitoring of key physiological and pharmacological parameters is an important part of a closed loop control system in critical care. Optical fiber sensors provide a versatile platform technology that can be easily incorporated into existing in-dwelling catheters or face masks. With appropriate functional coatings they can be used to monitor a range of relevant parameters and two different examples are presented: (i) respiration monitoring; (ii) drug level monitoring. Respiration monitoring involves monitoring of temperature and humidity in inhaled and exhaled breath. The optical fiber sensor consists of a fiber Bragg grating to measure temperature and a tip coating whose refractive index changes with humidity. The sensor is demonstrated to be able to track breath to breath changes when incorporated into a mask. Drug level monitoring is demonstrated in vitro using a long period grating coated with molecularly imprinted polymer nanoparticles that are sensitive to fentanyl. The sensor has a limit of detection of 50ng/ml.

Abstract
Chemo-radiation represents an effective therapy for carcinoma of the uterine cervix. The endometrium may however receive a consistent dose of mutagenic radiations and patients may have an increased risk of secondary malignancies. Endometrial mixed malignant mullerian tumor (MMMT) is a rare, highly aggressive disease, and neuroendocrine features are even rarer. A 68 years old woman underwent radio-chemotherapy for a squamous cell carcinoma of the cervix. Follow up was uneventful until, eight years after radio-chemotherapy, imaging exams detected a diffuse enlargement of the uterine body. Radical hysterectomy revealed a multiphasic lesion with both sarcomatous and mixed carcinomatous components. The carcinomatous, component presented neuroendocrine histologic and ultrastuctural features and an intense expression of neuroendocrine immunohistochemistry markers. No residual cervical carcinoma was documented (pR0). The patient died of disease after 9 months. Reported cases further demonstrate how the irradiation of the uterus for cervical cancer carries a not negligible risk of developing a second endometrial cancer. The second cancer may develop years after initial therapy and may have aggressive histologic and clinical features. This case underlines the importance for a long follow-up in women having received radio-chemotherapy alone.

Abstract
Octreotide and lanreotide, the first-generation somatostatin analogs, successfully control hormone hyperproduction, and related syndromes, in patients with acromegaly and neuroendocrine tumors. However, their anti-tumor effect, rather evident in large number of pituitary adenomas in acromegalic patients, has been hypothesized for a long time in patients with neuroendocrine tumors as well, although a significant tumor shrinkage has rarely been observed. However, the recent publication of the CLARINET study has strengthened the evidence, already emerged with the PROMID trial, that the long-term treatment with the first-generation long-acting somatostatin analogs may exert an anti-tumor activity on G1 and G2 enteropancreatic neuroendocrine tumors, as well. After the publication, majority of international guidelines have updated their algorithms in line with these results and this class of drugs obtained the indication as anti-tumor agents in the majority of patients with neuroendocrine tumors.

Abstract
Standardization in immunohistochemistry is a priority in modern pathology and requires strict quality control. Cost containment has also become fundamental and auditing of all procedures must take into account both these principles. Positive controls must be routinely performed so that their positivity guarantees the appropriateness of the immunohistochemical procedure. The aim of this study is to develop a low cost (utilizing a punch biopsy-PB-tool) procedure to construct positive controls which can be integrated in the patient's tissue slide. Sixteen frequently used control blocks were selected and multiple cylindrical samples were obtained using a 5-mm diameter punch biopsy tool, separately re-embedding them in single blocks. For each diagnostic immunoreaction requiring a positive control, an integrated PB-control section (cut from the appropriate PB-control block) was added to the top right corner of the diagnostic slide before immunostaining. This integrated control technique permitted a saving of 4.75% in total direct lab costs and proved to be technically feasible and reliable. Our proposal is easy to perform and within the reach of all pathology labs, requires easily available tools, its application costs is less than using external paired controls and ensures that a specific control for each slide is always available.

Abstract
A 4-year-old male with the diagnosis of T-cell acute lymphoblastic leukemia (T-ALL) relapsed after 19 months with an acute myeloid leukemia (AML). Immunoglobulin and T-cell receptor gene rearrangements analyses reveal that both leukemias were rearranged with a clonal relationship between them. Comparative genomic hybridization (Array-CGH) and whole-exome sequencing analyses of both samples suggest that this leukemia may have originated from a common T/myeloid progenitor. The presence of homozygous deletion of p16/INK4A, p14/ARF, p15/INK4B, and heterozygous deletion of WT1 locus remained stable in the leukemia throughout phenotypic switch, revealing that this AML can be genetically associated to T-ALL.

Abstract
The ultra-high vacuum (UHV) room temperature adsorption of benzotriazole (BTAH), a well-known corrosion inhibitor for copper, has been investigated on the pristine Au(111) surface using a combination of surface sensitive techniques. The dimensionality of the molecule is reduced from the 3D crystal structure to a 2-dimensional surface confinement, which induces the formation of hydrogen bonded 1-dimensional molecular chains consisting of alternating pro-S and pro-R enantiomers mainly. The 0-dimensional system is characteristic of gas-phase BTAH, which undergoes a tautomeric equilibrium, with consequences for the resulting adsorbed species. The balance between hydrogen bonding, inter-chain van der Waals interactions and surface-molecule interactions, and the correlation with the dimensionality of the system, are discussed in light of the experimental results and a computational description of the observed features.

Abstract
Segmental infarction (SI) of the testis is a rare condition that can masquerade as a mass lesion, thus requiring exclusion of tumour. If clinical exams do not exclude a neoplastic lesion with certainty, orchidectomy is usually performed. A case of SI of the testis is presented; the use of frozen section of the enucleated mass demonstrated the ischaemic nature of the lesion, so avoiding orchidectomy. The 8 year follow-up was uneventful. The use of frozen section in SI could permit the selection of cases in which testicular-sparing surgery should be considered.

Abstract
OBJECTIVES This study aims to compare breast cancer screening (BCS) and cervical cancer screening (CCS) practices of French women born to French parents with those of immigrants and nationals born to immigrants, taking their socioeconomic status into account. METHODS The study is based on data collected in 2010 in the Paris metropolitan area among a representative sample of 3000 French-speaking adults. For women with no history of breast or cervical cancer, multivariate logistic regressions and structural equation models were used to investigate the factors associated with never having undergone BCS or CCS. RESULTS We confirmed the existence of a strong gradient, with respect to migration origin, for delaying or never having undergone BCS or CCS. Thus, being a foreign immigrant or being French of immigrant parentage were risk factors for delayed and no lifetime screening. Interestingly, we found that this gradient persisted (at least partially) after adjusting for the women's socioeconomic characteristics. Only the level of income seemed to play a mediating role, but only partially. We observed differences between BCS and CCS which suggest that organized CCS could be effective in reducing socioeconomic and/or ethnic inequities. CONCLUSION Socioeconomic status partially explained the screening nonparticipation on the part of French women of immigrant origin and foreign immigrants. This was more so the case with CCS than with BCS, which suggests that organized prevention programs might reduce social inequalities.

Abstract
Background Food insecurity (FI) is the situation where people do not have, at all times, access to sufficient, safe and nutritious food that meets their dietary needs for an active and healthy life. The objectives of this study were to estimate the prevalence of FI in the Paris area by using, for the first time in France, a specific FI questionnaire and to identify the characteristics of food-insecure households, taking into account a potential neighbourhood effect. Methods This study is based on data from the third wave of the SIRS cohort study (a representative, population-based socioepidemiological study) that were analysed using a cross-sectional design. In 2010, 3000 individuals in the Paris metropolitan area (PMA) were interviewed. FI was investigated by means of the USDA’s HFSSM. We used stratified multilevel models across three household income categories to identify populations at risk for FI. Results In 2010, 6.30% (95% CI = [4.99-7.97]) of the households in the PMA experienced FI (up to 13.59% in the most underprivileged neighbourhoods). About 2.50% of the households experienced severe FI and 2.85% of household living with an income above 1666 € experienced food insecurity, whereas the percentage raises to 23.38% among those living below the poverty threshold (<791 €). Depending on the income level, different household characteristics emerged as being associated with FI. In the poorest households, the presence of a child under 3 years of age was associated with an increased risk of FI (OR = 2.11; p = 0.03). Among higher-income households, the household composition appeared to be strongly associated with FI. Conclusion FI exists in several social groups in France. Its prevalence in the most underprivileged households should be considered an indicator of vulnerability, which could permit targeted social assistance policies.

Abstract
OBJECTIVES To describe the individual characteristics associated with the absence of cervical smear (CCST); to investigate the role of residential neighbourhood, particularly practitioner density; and to explore changes in individual and contextual determinants after taking regular consulting in primary care for gynaecological health (RCGH) into account. DATA 1843 adult women from the SIRS survey conducted in 2005 in the Paris metropolitan area. Multilevel logistic regressions analysed factors associated with never-screening. RESULTS 10% of the women had never undergone CCST. Being single, less educated, of foreign origin, with no children, and without health insurance, having never worked, having never undergone a serious health problem and/or having nobody in their circle with cancer were associated with no CCST. Once adjusted on individual characteristics, living in a middle- (OR=1.95; IC=1.05-3.62) or in a lower-class neighbourhood (OR=2.31; IC=1.26-4.25) was associated with increased risks of never-screening, but neighbourhood physician density was not. Interactions were found between socioeconomic status and RCGH. Individual- and neighbourhood-level associations with CCST were different for women with or without an RCGH. CONCLUSION This study analysed individual and contextual inequalities in CCST practice in the Paris metropolitan area. To benefit from an RCGH did not seem to reduce all the social inequalities in CCST practice.

Abstract
OBJECTIVE The aim of our study was to investigate the moderating effect of school food programs in schools in disadvantaged neighborhoods on the association between household food insecurity and scholastic difficulties among adolescents. METHODS We analyzed data from the Social and Health Survey of Children and Adolescents in Quebec, Canada, which was conducted in 1999 and included 2346 adolescent students 13 and 16 years of age (and 1983 of their parents). Sample-weighted regression analyses were performed to determine the association between household food insecurity and school difficulties and to explore the moderating role of food supplementation programs with respect to this association. RESULTS Household food insecurity, which was linked to the indicators of family socioeconomic status, was strongly associated with the indicators of scholastic difficulties. This association disappeared for adolescents who benefited from food supplementation programs in schools in disadvantaged neighborhoods. The risk of school activity limitation decreased from OR = 2.76 (95% confidence interval [CI]: 1.41-5.41) to OR = 1.57 (95% CI: 1.35-3.40), the risk of below-average grades in the language of instruction decreased from OR = 2.19 (95% CI: 1.28-3.74) to OR = 0.59 (95% CI: 0.21-1.63), the risk of repeating a year decreased from OR = 2.14 (95% CI: 1.35-3.40) to OR = 0.87 (95% CI: 0.42-1.81), and the risk of self-rated poor academic performance decreased from OR = 1.74 (95% CI: 1.08-2.81) to OR = 0.81(95% CI: 0.37-1.78). CONCLUSION School food supplementation is a moderating factor in the association between household food insecurity and scholastic difficulties for adolescents.

Abstract
Recurrent hepatitis C is a common cause of graft loss in patients undergoing liver transplantation, and serial protocol liver biopsies have been used to identify patients at risk of graft loss from rapid fibrosis progression. The aim of this study was to derive a simple noninvasive index to predict fibrosis in patients with recurrent hepatitis C post-transplant. A retrospective study was performed assessing serial liver biopsies for post-transplant chronic hepatitis C infection. One hundred eighty-five patients were included in the analysis; median age 53 years (interquartile range 48-59) and 140 (76%) were male. Liver histology showed 53 (29%) had Ishak fibrosis stages F0/F1, 31 (17%) had F2, 29 (16%) had F3, 19 (10%) had F4 and 53 (29%) had F5/F6. The London Transplant Centres' (LTC) score was derived combining aspartate aminotransferase (AST IU/L), time from liver transplant (TFLT months), international normalized ratio and platelets. Diagnostic accuracy of the LTC score was assessed using area under receiver-operating characteristic (ROC) curves. The area under the ROC curve for moderate fibrosis (F >or= 2) was 0.78 (95% CI, 0.70-0.86; P < 0.0001), for advanced fibrosis (F4-6) was 0.80 (95% CI, 0.72-0.87; P < 0.0001) and for cirrhosis was 0.80 (95% CI, 0.72-0.88; P < 0.0001). An optimal cut-off value of 6.3 distinguished patients with no or mild fibrosis (F <or= 1) odds ratio 10.8 (95% CI, 5.1-22.9); P < 0.0001), sensitivity 88%, specificity 60%, negative predictive value 67% and positive predictive value 84%. The LTC score can identify patients with Hepatitis C virus recurrence following liver transplant with a low risk of significant fibrosis, thus avoiding the need for protocol biopsy.

Abstract
Historically, liver biopsy (LB) was the sole method to evaluate the severity of hepatic fibrosis in patients with chronic hepatitis C infection. However, LB is expensive and associated with a risk of severe complications. Therefore, noninvasive tests have been developed to assess the severity of liver fibrosis. The accuracy of Fibroscan (FS) and King's score (KS) was evaluated individually and in combination using liver histology as the reference standard. One hundred and eighty-seven patients were identified who had undergone a biopsy with a diagnosis of chronic hepatitis C virus (HCV) mono-infection (HCV RNA-positive by RT-PCR), attending King's College Hospital (n = 88) or the Royal Free Hospital (n = 99) (London) between May 2006 and December 2007. Liver fibrosis was scored using the Ishak method; significant fibrosis was defined as Ishak fibrosis stage F3-F6, and cirrhosis defined as Ishak fibrosis F5-F6. The diagnostic accuracy of each test was assessed by area under receiver operator characteristic curves (AUROC). Median age was 49 years (43-54) and 115 (61%) were male. The AUROC for FS, KS and FS + KS for the diagnosis of Ishak F3-F6 were 0.83, 0.82 and 0.85, respectively and for the diagnosis of cirrhosis (>or=F5) were 0.96, 0.89 and 0.93, respectively. The negative predictive values for the diagnosis of cirrhosis using the optimal cut-off results for fibrsocan (10.05 kPa), KS (24.3) and the two combined (26.1) were 98%, 91% and 94%, respectively. The noninvasive markers and, particularly, FS were effective tests for the prediction of cirrhosis in chronic hepatitis C. Both KS and FS also had clinical utility for the prediction of Ishak fibrosis stages F3-F6.

Abstract
BACKGROUND The microscopic assessment of squamous epithelium lesions in gastro-oesophageal reflux disease (GERD) is subjective. The Ki67 nuclear antigen expressed by proliferating cells provides an objective measure of regeneration in the squamous epithelium. AIM To evaluate Ki67 expression in GERD patients and controls, in comparison with histological lesions, pH-metry and endoscopic data. METHODS Eighty-seven patients with GERD symptoms and 20 symptom-free controls underwent endoscopy and 24-h pH monitoring. Oesophageal biopsies (4 cm, 2 cm and Z-line) were stained with Ki67/MIB-1 antibodies; the Ki67-positive nuclear area was assessed with an image analysis system and expressed as percentage of the whole epithelial area (Ki67-%). RESULTS Ki67-% was significantly higher in 32 patients with erosive oesophagitis, 44 endoscopy-negative GERD and 11 patients with functional heartburn than in controls (P = 0.0001). Both controls and patients showed a progressive increase in Ki67-% from 4 cm to the Z-line (P < 0.0001). Ki67-% showed a significant correlation with other conventional histological lesions (P ranged between 0.0151 and <0.0001). CONCLUSIONS Ki67 evaluation provides quantitative and objective data on squamous epithelium proliferative activity. This marker can be applied in the distinction of endoscopy-negative GERD from healthy controls.

Abstract
Weight gain induced by antipsychotics is the second most frequently given reason for noncompliance with pharmacologic therapy; excessive sedative effects rank first, with extrapyramidal side effects ranking third. Frequently, weight gain leads to inconsistent pharmacologic treatment; this exposes patients to the risk of recurrent symptoms. In fact, one of the key contributors to good clinical outcomes in schizophrenic patients is compliance with pharmacologic treatment. The goals of this study were to evaluate weight gain in a group of patients treated with olanzapine, diet modifications, and moderate physical activity and to compare the findings with those from a second group of patients who were given only olanzapine treatment. For 8 wk, investigators followed 2 groups of patients suffering from schizophrenia and hypomania in bipolar disorder, according to the nosographic criteria of The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). The first group (A) of 18 patients (9 female, 9 male) affected by manic episodes in bipolar disorder received olanzapine (10-20 mg/d), jogged lightly for 30 min 3 times a week, and complied with a diet that consisted of 500 kcal/d less than usual. The second group (B) of 10 patients (4 female, 6 male) with schizophrenia received only olanzapine (10-20 mg/d). All patients from both groups were weighed at the beginning of the observation period and weekly thereafter for 2 mo. After 2 mo of observation, group A showed a mean weight gain of 1.47 kg, whereas group B exhibited a mean weight gain of 3.5 kg; the difference between the 2 groups was almost 2 kg (P<.005). Group A showed a statistically significant reduction in weight gain compared with group B, clearly demonstrating the effectiveness of moderate physical activity and diet therapy in reducing weight gain in atypical antipsychotic treatment. Therefore, patient weight and body mass index must be monitored during the first weeks of antipsychotic treatment, with the goals of avoiding significant weight gain and treatment interruption.

Abstract
Gastric cancer develops through the accumulation of multiple genetic lesions that involve oncogenes, tumor suppressor genes and DNA mismatch repair genes. Lauren's classification of gastric carcinoma does not correlate with cellular phenotypes expressed by neoplastic cells and gastric and intestinal cell differentiation markers are widely expressed in both types (intestinal and diffuse) of gastric carcinoma. In contrast, the study of the correlation between morphologic events and genetic alterations, which come about in the cancerogenetic process, seems to indicate the existence of distinct cancerogenetic pathways for the intestinal (or glandular) and diffuse type carcinoma, both originating from a HP-positive gastritis. In particular there seem to be three different profiles of cancerogenesis: 1) p53 mutations which accompany the onset of dysplasia and intestinal-type carcinoma; 2) DNA repair mechanism alterations conditioning microsatellite instability, seem mutually exclusive with regards to p53 mutations. Microsatellite instability correlates with antrally located intestinal-type carcinoma, with little metastatic tendency and a better prognosis; microsatellite instability frequently involves the TGF beta RII, IGF II R genes or the BAX proapoptotic gene, in as much as these contain microsatellite sequences; 3) alterations of E-cadherin, both with regards to mutations and abnormal expression. These lead to junctional and cell polarity loss and are primarily associated with diffuse type carcinoma, which is characterized by poorly cohesive neoplastic cells. Some tumors, initially arising as intestinal-type (glandular structure), acquire a mixed histotype during neoplastic progression, in which both the typical alterations of the intestinal cancerogenesis (p53, microsatellite instability) and those of the diffuse carcinoma (E-cadherin) coexist. The identification of a mixed histotype could have importance both in epidemiologic, pathogenetic and prognostic terms.

Abstract
BACKGROUND The aim of this study was to identify and stratify the most important preoperative factors for in-hospital death after surgery for type A aortic dissection. METHODS From January 1985 to June 1998, 108 patients underwent surgery for type A aortic dissection. 89.9% of the patients had an acute type A dissection (AD), whereas 11.1% had a chronic dissection (CD). Cardiac tamponade and shock occurred in 22% and 14.8% of the patients, respectively. The location of the primary intimal tear was in the ascending aorta in 71.2% of the cases, in the arch in 16.6% and in the descending aorta in 7.4%. Univariate and multivariate analyses were conducted to identify non-embolic variables independently correlated to in-hospital death. A predictive model of in-hospital mortality was then constructed by means of a mathematical method with the variables selected from logistic regression analysis. RESULTS The overall in-hospital mortality rate was 20.3% (22/108 patients), being 9% for CD and 21.6% for AD. Emergent procedures had an in-hospital mortality rate of 47.6%, whereas non-emergent operations had an in-hospital mortality rate of 13.7% (p<0.01). Univariate analysis revealed among 39 preoperative and operative variables, age (years), age >70 years, remote myocardial infarction, cerebrovascular dysfunction, diabetes, preoperative renal failure, shock, cardiopulmonary bypass time (minutes), emergency operation as factors associated to in-hospital death (p<0.05). Stepwise logistic regression analysis selected as independent predicting variables (p<0.05), remote myocardial infarction (p=0.006), preoperative renal failure (p=0.032), shock (p=0.001), age >70 years (p=0.007). Finally, a probability table of death risk was obtained with the logistic regression coefficients. The lower death probability (10.6%) was calculated in absence of risk variables; the higher one in presence of all of them (79.7%). Between these extremes, a total of 64 combinations of death risk were obtained. CONCLUSIONS Increasing age, shock, coronary artery disease and renal failure are variously associated to a high risk of in-hospital death after surgical correction of type A aortic dissection. This predictive model of death probability allows to collocate preoperatively patients with type A aortic dissection at different levels of risk for in-hospital death.

Abstract
OBJECTIVE Analysis of figures and characteristics of suicide behaviour in the area of Varese and the neighbouring northern towns (Valceresio, the valleys around Luino and northern Verbano), with the purpose of finding out preventing measures. DESIGN Epidemiological-descriptive survey. The 1995-1997 ISTAT death cards, included in the death files of the former USSL of Varese have been taken into consideration. Only those people who were resident at the suicide moment have been included in the survey. Afterwards the psychiatric service archives were consulted, to find any possible contact between the subjects in the ISTAT files and the psychiatric services themselves. With regard to these patients, some information such as suicide attempts, psychiatric pathology and first contact with the psychiatric services have been pointed out. SETTING Arcisate, Cittiglio, Luino and Varese districts, where the Community Mental Health Services 1 and 2 of "Azienda Ospedaliera Universitaria Macchi" of Varese operate. MAIN OUTCOME MEASURES The suicide rates in the studied area have been reckoned and, through direct standardization, the rates of the single districts have been compared. RESULTS There were 78 suicides (24 females and 54 males): rate of 8.2 per 100,000. In accordance with the national trend, there is evidence of a general reduction of the suicide phenomenon, except among the youngest. Districts of Luino and Arcisate are geographic areas to examine in the time, because a wider sample could reveal a higher risk. Young and elderly people are the most affected among the males and, 55/64-year-old people, both males and females, are at higher risk. Suicide methods vary with the age. A high percentage of subjects are not married and with low education. Less than one third of the subjects had come into contact with the psychiatric service. CONCLUSIONS These data allow a comparison with the national survey and an analysis of the suicide features in the study area. The purpose is to elaborate preventing strategies with multi-dimensional approach whose efficacy may be proved in the future by setting up a provincial observatory.

Abstract
We examined the estrogen receptor measurement in 265 human breast cancer cytosols by using a specific method based on [3H]tamoxifen aziridine labeling, sequential immunoadsorption with an antiestrogen receptor monoclonal antibody (H-222), sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and autoradiography. These new tools of molecular endocrinology revealed an impressive estrogen receptor molecular polymorphism. Given the recent finding of a similar estrogen receptor polymorphism at the messenger RNA level by several laboratories, it is tempting to speculate about its possible biological significance. To gain insight into the potential clinical relevance of this polymorphism in terms of breast cancer hormone dependence, we compared the 265 cytosols for their [3H]tamoxifen aziridine- and [3H]estradiol-binding capacities using the above-mentioned method and the conventional dextran-coated charcoal assay. We failed to identify a specific [3H]tamoxifen aziridine electrophoretic pattern with respect to the tumor estrogen receptor content as measured by the dextran-coated charcoal assay. However, an excellent correlation overall was found between the intensities of both labeling methods. Some tumors were positive for only one of these two ligands. It will be clinically important to see whether the tumors positive for [3H]tamoxifen aziridine only correspond to the small subset of tumors (10%) which respond to tamoxifen treatment despite very low estrogen receptor levels, as measured by the dextran-coated charcoal technique.

Abstract
A simple sandwich ELISA method has been developed for the quantification of soluble HLA class I antigens (s-HLA) in human serum. The assay utilizes the monoclonal antibody Q6/64, directed to a monomorphic determinant of the HLA alpha-chain, to capture the antigen and the biotinylated NAMB1 monoclonal antibody, directed to beta 2-microglobulin, as the detection antibody. The extract of the LG-2 lymphoid cell line and pooled sera from 100 healthy subjects are utilized as standards. The arbitrary value of 100 s-HLA Relative Units/mL (RU/mL) is given to the 1:20 dilution of pooled human sera whose optical density value corresponds to the one of the extract of 1 x 10(6) LG-2 cells (6.25 micrograms/mL protein concentration). The assay is easy to perform, specific, reproducible (intra- and inter-assay variations ranging from 3.2% to 8.87%), sensitive (detection limit of 6 RU/mL), and needs a small amount of serum (0.1 mL). The mean serum levels of s-HLA found in 100 healthy normal subjects are 41.9 +/- 13.4 RU/mL. The potential uses of the method are discussed.

Abstract
A reagent is described for the colorimetric enzymic determination of high-density-lipoprotein (HDL) cholesterol. The reagent can be used with HDL fractions isolated by the various methods of precipitation of low- and very-low-density lipoproteins we investigated. The considerable sensitivity obtained by use of Barham-Trinder's reaction allows the sample/reagent volume ratio to be decreased to 1:80, and major interferences thus eliminated. The response is linear from 100 to 2000 mg of HDL cholesterol per liter. The maximum CV obtained in precision tests was approximately 1% within series and approximately 3% between series. Most of the bilirubin interference is eliminated by adopting a reaction pH of 6.1. Because of its sensitivity, the reagent is particularly suitable for use with HDL fractions isolated after precipitation with polyethylene glycol 6000, which are characterized by a marked dilution. HDL cholesterol determination with the proposed reagent is accurate and precise. Values obtained are in line with those provided for by the Abell-Kendall method. The method can easily be automated.
