Focus on the Correlations between Alzheimer's Disease and Type 2 Diabetes.

Background: In the last decades, both diabetes mellitus and Alzheimer's disease are constantly increasing. Affected individuals, therefore, represent an enormous problem for the society, governments and global organizations. These diseases are usually considered as independent conditions, but increasing evidence shows that there are links between these two disorders.

Ultrasound features of medullary thyroid carcinoma correlate with cancer aggressiveness: a retrospective multicenter study.

Background: Poor prognosis of medullary thyroid cancer (MTC) with suspicious ultrasound (US) features has been reported. The aim of the study was to investigate the association between preoperative US presentation and aggressiveness features of MTC. Also, US features of MTC were compared with those previously reported.

Properties of the endogenous components of the thioredoxin system in the psychrophilic eubacterium Pseudoalteromonas haloplanktis TAC 125.

The endogenous components of the thioredoxin system in the Antarctic eubacterium Pseudoalteromonas haloplanktis have been purified and characterised. The temperature dependence of the activities sustained by thioredoxin (PhTrx) and thioredoxin reductase (PhTrxR) pointed to their adaptation in the cold growth environment. PhTrxR was purified as a flavoenzyme and its activity was significantly enhanced in the presence of molar concentration of monovalent cations.

Development and validation of predictive MoSaiCo (Modello Statistico Combinato) on emergency admissions: can it also identify patients at high risk of frailty?

The prospective historical cohort study develops and validates a method of identifying patients at high risk of emergency admission to hospital in the population of the Province of Ravenna (no. = 296 641). The main outcome measure is: emergency hospital admission analyzed using multivariate logistic regression (MoSaiCo - Modello Statistico Combinato).

Molecular and functional characterization of polynucleotide phosphorylase from the antarctic eubacterium Pseudoalteromonas haloplanktis.

Polyribonucleotide phosphorilase from the psychrophilic Antarctic eubacterium Pseudoalteromonas haloplanktis (PhPNPase) has been purified. This enzyme catalyzes both the RNA polymerisation and degradation reaction, showing the highest activity at temperatures below 40 degrees C. PhPNPase is quite sensitive to heat treatment and it is endowed with remarkable halotolerance.

Differential cold-adaptation among protein components of the thioredoxin system in the psychrophilic eubacterium Pseudoalteromonas haloplanktis TAC 125.

Thioredoxin and thioredoxin reductase from the psychrophilic eubacterium Pseudoalteromonas haloplanktis were obtained as recombinant His-tagged proteins (rPhTrx and rPhTrxR, respectively). rPhTrxR is organised as a homodimeric flavoenzyme, whereas rPhTrx is a small monomeric protein, both containing a functional disulfide bridge. However, three additional cysteines are present as free thiols in purified rPhTrxR.

Increased metastatic lymph node 64 and CYP17 expression are associated with high stage prostate cancer.

The metastatic lymph node 64 (MLN64), which is localized in the human chromosome 17, encodes a protein with strong homology with steroidogenic acute regulatory protein. Its overexpression in human breast carcinomas and MLNs led to the hypothesis that this protein could be involved in intraneoplastic steroidogenesis. In the present study, we investigated the expression of MLN64 in prostate cancer, another hormone-dependent tumor, and compared its expression with that of CYP17, the gene encoding for the key enzyme of androgen synthesis.

The IGF axis in prostate cancer.

Prostate cancer, the most frequent non-cutaneous malignancy in men from industrialized countries, is a growing medical problem, representing the second leading cause of male cancer deaths. In the last decade, converging evidence from epidemiological and biological studies suggests that the Insulin-like Growth Factor (IGF) axis is involved in the tumorigenesis and neoplastic growth of prostate cancer. Epidemiological observations indicated that circulating IGF-I levels are positively associated with the increased risk of prostate cancer.

[Development and first implementation of an instrument to measure the social relations network in a town].

A programme of personal relationships improvement is under way in the town of Trento in Northern Italy. It was decided to carry out a survey to describe the frequency and quality of interpersonal links as a baseline. A questionnaire to assess frequency and quality of interpersonal relationships has been validated (QRI) and a first description of its distribution in a representative sample of Trento population has been achieved.

Objectives: to describe occupational accidents among foreign women working in two regions of North-Eastern Italy, in the perspective of a desirable prevention policy.

Setting And Design: frequency distribution of occupational accidents among foreign women covered by the National Institute for Insurance against Work Accidents (INAIL) in 2000.

Participants: foreign female workers employed in two regions of North-Eastern Italy.

[Health profile of a population as a predictor of health resources utilization: results of the implementation of an epidemiologic model for needs analysis].

The integration of the scientific researches in the assistance process is one of the most important challenges that is currently set to the health operators. In this paper a model for the health needs-assessment will be applied to verify if and how the prevalence of some classical risk factors for cardiovascular disease foretells mortality and hospitalisation episodes at 3 years, and if it could express the health need of that population. The "sanitary history" of 1704 subjects, enrolled in 1996 during the Brisighella Study, has been followed.

Long-term persistence with antihypertensive drugs in new patients.

The objective of this study was to investigate stay-on-therapy patterns over 3 years among patients prescribed different classes of antihypertensive drugs for the first time. A retrospective analysis of information recorded in the drugs database of the Local Health Unit of Ravenna (Italy) was carried out on 7312 subjects receiving a first prescription for diuretics, beta-blockers, calcium channel blockers, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II antagonists between 1 January and 31 December 1997. Patients were followed up for 3 years.

Pharmacoutilization of antihypertensive drugs: a model of analysis.

Objectives: To identify clinical and economic indicators of pharmacoutilization of antihypertensive drugs.

Patients And Methods: 4614 subjects receiving a first prescription for amlodipine, atenolol, fosinopril, indapamide, or losartan were included in the study. All prescriptions filled during the study period from January 1, 1997 to December 31, 1998 were considered.

Regional variations of insulin-like growth factor I (IGF-I), IGF-II, and receptor type I in benign prostatic hyperplasia tissue and their correlation with intraprostatic androgens.

Benign prostatic hyperplasia (BPH) is an androgen-dependent disease; it originates exclusively in the inner prostate, which includes tissue surrounding the urethra. Stromal-epithelial interaction has a pivotal role in the regulation of the development and growth of the prostate, and locally produced peptide growth factors are considered important mediators of this interaction. Insulin-like growth factor I (IGF-I) and IGF-II, acting mainly through type 1 IGF receptor (IGFR1), have mitogenic and antiapoptotic effects on epithelial and stromal prostatic cells.

[Epidemiologic model for the assessment of health needs].

Health is a high priority in public health planning, a process by which health, services and resources are connected to each other. Assessing peoples health needs is one of the most difficult tasks, because of the lack of information on the spread of diseases, the seriousness of them and their capacity to disable, as well as the lack of timely and appropriate information on them. The epidemiological model put forward describes the volume of resources necessary to maintain the health needs of a population as depending upon the prevalence of diseases, the health services used to combat these diseases and the consequent human and financial resources employed.

Hyperandrogenism in the adolescent female.

Hirsutism in adolescent girls commonly starts as an esthetic problem in young women and is later complicated by the development of infertility and polycystic ovary syndrome, which are frequent consequences of prolonged hyperandrogenism. To ascertain whether particular prepubertal clinical manifestations may predict the development of adolescent hirsutism, we followed 70 girls with precocious pubarche (PP) with or without prepubertal hypertrichosis (PH) until 3 years (mean age 14.8 +/- 0.

Synergistic transcriptional activation of the thyrotropin receptor promoter by cyclic AMP-responsive-element-binding protein and thyroid transcription factor 1.

In this study we have investigated the molecular mechanisms involved in hormonal induction of thyroid-specific transcription of the thyrotropin receptor (TSHr). A cyclic AMP-responsive element (CRE) has been characterized in the minimal TSHr promoter, and promoter activity shown to be also induced by thyroid transcription factor 1 (TTF-1). We here describe a cooperative effect between TTF-1 and CRE-binding protein on the TSHr promoter.

[SO2 air pollution and hospital admissions in Ravenna: a case-control study].

The association between air pollution and hospital admission for chronic respiratory and ischemic heart diseases was analyzed through a case-control approach. The study was based on routinely available data in Ravenna and covered the period 1986-88. A control group (n = 37250) was used to evaluate the specificity of the health effects of air pollution.

Purification and characterization of thyroid transcription factor 2.

Thyroid transcription factor 2 binds to the promoters of both thyroglobulin and thyroperoxidase genes, two markers of thyroid tissue differentiation, and its binding modulates the activity of both promoters. In this paper we describe the purification of thyroid transcription factor 2 essentially to homogeneity and demonstrate that it is a thyroid-specific DNA-binding protein. Furthermore, we provide a biochemical characterization suggesting that thyroid transcription factor 2 binds to DNA as a dimer and that it is a zinc-finger DNA-binding protein regulated in vitro by the redox state.

The thyroid hormone inhibits the thyrotropin receptor promoter activity: evidence for a short loop regulation.

Thyrotropin, by binding its specific receptor on the plasma membrane of the thyrocyte, regulates thyroid function and differentiation. In FRTL5 cells, thyrotropin down-regulates the thyrotropin receptor (TSHr) promoter activity and induces the transcription of the alpha form of thyroid hormone receptor (TR-alpha 1). In this study we show that the thyrotropin receptor down-regulation, induced by thyrotropin, is mediated by TR-alpha 1.

Thyroid transcription factor 1 activates the promoter of the thyrotropin receptor gene.

The TSH receptor (TSHr) is one of the most important thyroid differentiation markers. The binding of the TSH hormone to its receptor is an essential step in the modulation of thyroid function and differentiation. Here we report that the thyroid transcription factor 1 (TTF1), a transcription factor essential for thyroid-specific gene expression, binds to the TSHr minimal promoter.

Decline of incidence of A, B and non-A, non-B hepatitis in Italy. Results of four years surveillance (1985-88). SEIEVA collaborating group.

A specific surveillance system for acute viral hepatitis which uses weekly notification of cases and a standard risk factor questionnaire was started in Italy in 1984. From 1985 to 1988 153 Health Departments (27% of Italian population) joined the system. Estimated incidence of reported viral hepatitis was 30 per 100,000 in 1985 and 14 in 1988.

The role of antiseptics and disinfectants in the control of nosocomial infections.

More than 600,000 cases per year of nosocomial infection in Italy reflect, in part, the scant attention given to the vehicles of infection, conditions which favour cross-contamination and not least to the inappropriate use of antiseptics and disinfectants in our hospitals. Disinfection procedures are intended to remove or neutralise sources of potentially pathogenic organisms or to prevent their transmission by blocking the routes of transmission. Data to support many disinfection policies, particularly those of routine disinfection of inanimate surfaces, i.
