[Osteoporosis and diabetes].
2011
Diabetes mellitus and osteoporosis are chronic diseases with an elevated and growing incidence in the elderly. Recent epidemiological studies have demonstrated an elevated risk of hip, humerus and foot fractures in elder diabetic subjects. While type 1 diabetes is generally associated with a mild reduction in bone mineral density (BMD), type 2 diabetes, more prevalent in old subjects, is frequently linked to a normal or high BMD. Studies on experimental models of diabetes have suggested an altered bone structure that may help to explain the elevated risk of fractures observed in these animals and may as well help to explain the paradox of an incremented risk of fractures in type 2 diabetic …
Steroid-growth factor interaction in human prostate cancer. 2. Effects of transforming growth factors on androgen metabolism of prostate cancer cells
1996
The ability of human prostate cancer cells to metabolize androgens was assessed through administration of physiological concentration (0.5-10 nM) of tritiated testosterone (T) as precursor and one-step analysis of both T degradation and products' formation by reverse-phase HPLC and on-line radioactive detection after either 24 h or 72 h incubation. Overall, different prostate cancer cells degraded T quite differently, favoring alternatively reductive or oxidative metabolic pathways. In particular, both LNCaP and DU145 cells retained high levels of unconverted T, with a limited production of androstenedione and its 17-keto derivatives and relatively high amounts of dihydrotestosterone (DHT) …
Prevalence and risk factors of delirium in the intensive care unit: An observational study
2020
Background: Several risk factors, such as age, alcohol abuse, dementia, and severe illness, can contribute to the development of delirium. However, limited information is available in the literature regarding the risk of delirium among surgical, trauma, neurological, and medical intensive care patients. Aims and objectives: To describe the prevalence of risk factors associated with delirium in intensive care units. Design: This study used an observational design. Methods: We enrolled 165 patients hospitalized in two intensive care units in Italy. Patients were first evaluated using the Prediction of Delirium model and were subsequently evaluated using the Intensive Care Delirium Screening C…
The prevalence of musculoskeletal disorders and low back pain among Italian nurses. An observationalstudy
2020
Background and aim of the work: Musculoskeletal disorders and low back pain have negative impact amongst Italian nurses who work in hospital. Nursing staff are known to be at risk of developing back disorders, where low back pain has a prevalence from 16% to 60% in the world. This study aims to determine the prevalence of musculoskeletal disorders and low back pain among nurses who working in a Roman hospital. Methods: Cross sectional study was carried out in an Italian hospital and the Nordic Musculoskeletal Questionnaire-IRSST was administered to 256 registered nurses. Logistic regression analyses were performed to understand risk factors associated with pain. Results: Nurses reported dif…
Improving operating room efficiency: an observational and multidimensional approach in the San Camillo-Forlanini Hospital, Rome
2017
SCOPO.Le sale operatorie (SOs) sono strutture organizzative caratterizzate da un elevato grado di comples- sità organizzativa e gestionale che pone un attento monitoraggio dei processi produttivi, in una logica “spendingreview”. Pertanto diviene necessario pianificare interventi di miglioramento ove questi siano applicabili. È in questo contesto che è stata realizzata questa indagine, al fine di migliorare l’efficienza del servizio reso a parità di costi METODI. E’ stato realizzato una analisi organizzativa tra i mesi di Aprile e Dicembre 2016 su un blocco operatorio dell’azienda ospedaliera, applicando la metodologia “process management” alla realtà delle SOs. Il progetto ha coinvolto due …

The Pomar Codex (ca, 1590): plants and animals of the old world and from the Hernandez expedition to America.
1992
Abstract<title> RIASSUNTO </title>Si descrive un codice illustrato (ca. 1590), donato dal re Filippo II a Honorato Pomar, professore di medicina botanica all'Università di Valencia, e ora conservato nella biblioteca della stessa universita. Tale codice contiene 218 acquarelli di piante e animali del Vecchio Continente e provenienti dalla spedizione nelle Americhe di Hernandez (1571-1577). Inoltre, l'articolo si sofferma brevemente sull'interesse di Filippo II per la storia naturale, sulla spedizione di Hernandez e sulla cattedra di botanica medica all'universita di Valencia nel corso del sedicesimo secolo. Infine, si discute dell'identita dell'autore delle illustrazioni e dei te…

Organización del trabajo y culturas laborales en los feminizados almacenes de la globalización agroalimentaria
2021
La globalización del sistema agroalimentario ha transformado la organización del trabajo en los campos y almacenes agrícolas. El almacén de manipulado y confección de frutas y hortalizas constituye un lugar clave para analizar las estrategias de acumulación de la agroindustria y sus efectos sobre la organización social del trabajo, en particular, la relación entre estas estrategias y los procesos de feminización y desvalorización del trabajo agrícola. Una desvalorización del trabajo femenino que es un elemento clave en la competitividad del sector agrícola y se apoya –y legitima– en una cultura del trabajo determinada. Este artículo examina la forma que adquiere esta relación y sus implicac…
