A critical appraisal of the intrinsic pancreatic angiotensin-generating system
The pancreas is a relative newcomer to the stable of tissues with an intrinsic angiotensin-generating system. The involvement of this system in pancreatic activity will be dependent on the angiotensin-generating paths present in the pancreas and their precise cellular location. Thus far, renin, angiotensin-converting enzyme (ACE), angiotensin II and AT1 and AT2 receptors have been found. These are components of the "classical" renin-angiotensin system. But there is uncertainty as to their location and site of action. Furthermore, it is not known which, if any, alternative enzymes to renin and ACE are present, which angiotensins in addition to angiotensin II are generated and whether or not there are receptors to angiotensin IV and angiotensin-(1-7). Future research should focus on these aspects in order to provide a mechanistic basis to pancreatic physiological functions and to pathological conditions of clinical relevance
Risk assessment, and carcinogen mutagen for workers potentially exposed in the research laboratories of “Sapienza” University of Rome for Health Surveillance
The following work is meant to represent the evaluation of risk factors for the health of exposed workers, arising from the management of carcinogenic and mutagenic substances, through the use of algorithms. In some places of work as a research laboratory, it is more suitable a theoretical and practical methodology (algorithm) which allows a "timely" exposure assessment. The methodology developed and used is able to determine the level of risk of exposure due to a single agent and / or to more agents. Results obtained by the algorithm, have shown an higher exposure to 1 for formaldehyde (Lcanc = 1.32), while for acrylamide results obtained shows a lower exposure to 1 (Lcanc = 0.528). Although the overall exposure level of studied workers higher value to 1 (Lcanc= 1.848), the Occupational Medicine Centre of "Sapienza" - University of Rome, in agreement with the position taken by the Italian Society of Occupational Medicine and Industrial Hygiene applies health surveillance even in the presence of potential health risk reducing it among the general protection measures the health and safety of workers
Requirements for cabin crew medical examinations and assessments
The aim of the current study is to review current regulations relatively to medical requirements necessary to achieve suitability to fly of the cabin crew. There are three classes of flight crew medical standards and licensing. A first class medical certificate is required for all pilots who perform professional flights or skydiving instructors. A second class medical certificate is required only for persons who do not perform professional flights, skydiving activities or any other professional activity related to aircraft piloting (cabin crew, holders of Light Aircraft Pilot’s Licence - LAPL, remote pilot operators). Finally, a third class medical certificate is required for workers engaged in air traffic control
Are bank employees stressed? job perception and positivity in the banking sector: an italian observational study
Background: The epidemiology of stress on bank workers in Europe is only at the introductory stages. This study investigated for the first time the association between occupational stress level in bank-employees using the BEST8, Karasek-Model and socio-demographic and working factors in Italy. Methods: The observational pilot study involved 384 employees. Three questionnaires were adopted to collect data: Karasek-Model, BEST8 (p < 0.001) and Positivity-Scale. Results: 25% of the sample belonged to high stress group. The workers more stressed were older with a commercial role and consumer of antidepressants/sedatives. Women were much more likely to agree with the perception of feeling unsafe in a possible robbery (OR = 2.42; 95% CI: 1.50-3.91) and with that sales requests were in conflict with one's own personal moral code (OR = 2.31; 95% CI: 1.38-3.87). Older employees declared feeling inadequate in the workplace (OR = 1.97; 95% CI: 1.07-3.65) and younger employees referred to be anxious about meeting financial budget goals. Workers who had a low positivity had a lower probability of adaptation (OR = 0.88; 95% CI: 0.83-0.93). Conclusions: The occupational stress level in the banking sector involves many aspects: gender, type of bank, role, personal morals, high job-demands, low level of decision-making. This study recommended that banks should implement strategic interventions for well-being of employees, and consequently for their productivity
Il rischio biologico da virus dell’epatite B e C (HBV e HCV): prevenzione specifica e sorveglianza sanitaria in ambiente ospedaliero alla luce del D.Lgs. 81/08.
Il rischio di infezione da patogeni a trasmissione ematica in ambiente sanitario è un fenomeno ben riconosciuto ed è riconducibile a tre modalità : nosocomiale propriamente detta (dall’ambiente ai pazienti oppure crociata tra pazienti); occupazionale (da paziente infetto ad operatore); da operatore infetto a paziente. Il presente lavoro affronta il problema rilevante di sanità pubblica determinato dai virus epatitici B (HBV) e C (HCV) trasmissibili per via ematica e definisce le raccomandazioni per contenere l’infezione da operatori infetti ai pazienti. In particolare, gli obiettivi specifici riguardano le eventuali condizioni in cui limitare le attività degli operatori sanitari infetti e stabilire la necessità di eseguire lo screening
Gaetano Pieraccini: Public Health giant who created Italian Social Medicine
It’s well known all over the world that Italy is the birthplace of Bernardino Ramazzini (1633 - 1714), the real founder of occupational medicine, and that Italian doctors had a great importance in scientific and cultural development in occupational medicine. One of the most celebrated of them was Luigi Devoto, Professor of Medical Pathology at Pavia in 1901, who undertook a free course of Occupational medicine, creating in the same year the fortnightly journal "Work" - that became "Occupational medicine" since 1925 - and opening a Labour Clinic in Milan in 1910. In 1907 the first two Italian schools of occupational medicine arose in Milan and in Naples. In 1901 Giulio Yule Giglioli wrote the first systematic treatise about workers’ diseases. In this cultural background Gaetano Pieraccini grew and developed his original cultural approach to the field of occupational medicine, which got from him a new dimension: the Social Medicine

Cellular and ultrastructural location of angiotensinogen in rat and sheep kidney
Cellular and ultrastructural location of angiotensinogen in rat and sheep kidney. Recent evidence suggests the involvement of a local renin-angiotensin system in some renal actions of angiotensin II (Ang II). In this study the renal distribution of the precursor to angiotensin formation, angiotensinogen, was investigated in rats and sheep using immunohistochemistry, immunoelectron microscopy and non-isotopic hybridization histochemistry. Immunostaining for angiotensinogen was seen in proximal tubules (PCT) of both rat and sheep kidneys. In the rat the strongest immunostaining was found in the kidneys of neonatal (1 day old) rats. Staining declined after birth. Non-isotopic hybridization histochemistry using oligodeoxynucleotide probes labeled with biotin confirmed the presence of angiotensinogen mRNA expression in PCT of the rat renal cortex. Electron microscopic immunohistochemistry using antibodies raised against rat angiotensinogen showed weak staining in the adult of granule-like structures close to the apical membrane of PCT cells. In the neonatal rat kidney, angiotensinogen immunostaining was found throughout the PCT cells and was markedly stronger than that seen in adult rat kidney. In sheep, angiotensinogen immunostaining with an antibody raised against purified ovine angiotensinogen showed staining of PCT in fetal, newborn and adult sheep kidney. The strongest immunostaining seen was in fetal sheep kidney with a decline seen after birth. Reverse transcription polymerase chain reaction (RT-PCR) showed that angiotensinogen mRNA was expressed in the sheep kidney at all ages studied. Angiotensinogen expression was higher in fetal sheep kidneys (77 day and 141 day gestation) than in adult sheep kidney. In conclusion, angiotensinogen mRNA expression was detected in both rat and sheep kidneys. Immunostaining showed angiotensinogen protein in PCT cells of the renal cortex. Angiotensinogen staining and mRNA expression is highest during development and declines in the adult
Association between work related stress and health related quality of life: the impact of socio-demographic variables. A cross sectional study in a region of central Italy
The aim of this work is investigate relationship between health-related quality of life and work-related stress and the impact of gender, education level, and age on this relationship. A cross-sectional study was conducted among workers of various setting in Rome and Frosinone. Work-related stress was measured with a demand-control questionnaire and health-related functioning by SF (short form)-12 health survey. There were 611 participants. Men reported high mental composite summary (MCS) and physical composite summary (PCS). In multivariate analysis age, gender (p < 0.001) and job demand (0.045) predicted low PCS. Low MCS predicted poor PCS. Job demand and educational level resulted negatively associated with MCS. In an analysis stratified for age, gender, and educational level, gender and age resulted effect modifier for MCS, gender and education level for PCS. In women increase of decision latitude predict (p = 0.001) an increase in MCS; a low job demand predict high MCS in male (p ≤ 0.001). In younger workers, a lower level of job demand predicted high MCS (<0.001). For PCS, gender and education level resulted effect modifier. In women, high decision latitude predicted higher PCS (p = 0.001) and lower level of job demand results in higher PCS (p ≤ 0.001). Higher educational level resulted predictor of low PCS. Management of risk about work-related stress should consider socio-demographic factors
Preventive medicine center and health care for students of medicine and health professions at the Sapienza University of Rome: a research protocol
This project aims to develop a Center of Preventive Medicine and Health Care for the students of Medicine and Health profession
at Sapienza University of Rome. At the beginning of the university career students, both residents and nonresident s, have to face
several difficulties such as: starting smoking or the increase in cigarette consumption ; the independent management of their own
health (especially for non residents consequently to the distance of the family doctor) ; unhealthy diet; tuberculosis (TB) biological
risk during their university training. These aspects , especially if present at the same time, act as a source stress and adversely affect
the quality of life and the academic performance. Specific aims of the project will be: implementing an ambulatory of Preventive
Medicine; implementing a virtual ambulatory of general medicine; creating a website on the problems mentioned above. Data
collected will be computerized to keep an electronic health record (HER) and to use the information for the purposes of scientific
research. The Centre will act in close relationship with the Central Administration, with the Headmasters of the Medical Faculties,
and in close collaboration with the Center of Occupational Medicine of Sapienza University
