Drug Prescription and Delirium in Older Inpatients: Results From the Nationwide Multicenter Italian Delirium Day 2015-2016
2019
Objective This study aimed to evaluate the association between polypharmacy and delirium, the association of specific drug categories with delirium, and the differences in drug-delirium association between medical and surgical units and according to dementia diagnosis. Methods Data were collected during 2 waves of Delirium Day, a multicenter delirium prevalence study including patients (aged 65 years or older) admitted to acute and long-term care wards in Italy (2015-2016); in this study, only patients enrolled in acute hospital wards were selected (n = 4,133). Delirium was assessed according to score on the 4 "A's" Test. Prescriptions were classified by main drug categories; polypharmacy w…
Regulation of noradrenergic coerulean neuronal firing mediated by 5-HT2 receptors: involvement of the prepositus hypoglossal nucleus.
1991
Abstract Previous studies have indicated a 5-HT2-mediated inhibitory influence on unit activity in the locus coeruleus. In the present work, attempts were made to determine which area(s) of the brain is (are) involved in this effect: (1) Microiontophoretic application of serotoninergic compounds (quipazine, ketanserin, RU 24969 (Roussel Uclaf), 8-hydroxy-2(di-n-propylamino) tetralin (8-OH-DPAT), metergoline, serotonin) in the locus coeruleus, did not alter the coerulean discharge. Local microinjection of quipazine or ketanserin in the area of the locus coeruleus, as well as in one of its major afferents, the prepositus hypoglossi, had no effect on the unit activity in the locus coeruleus. 1…
Comparative investigations on the actions of ACTH1-24, somatostatin, neurotensin, substance P and vasopressin on locus coeruleus neuronal activity in…
1987
A considerable number of neuropeptides have been localized immunohistochemically in the area of the locus coeruleus of the rat. The objective of this study was to assess the actions of some of these transmitter candidates on spontaneously active locus coeruleus neurons in vitro. The effects of bath-applied peptides on the discharge rate of individual locus coeruleus neurons were investigated. A midpontine slice preparation of the gerbil brain was used. Excitatory dose-dependent effects were found with four peptides with the following rank order of potency: Substance P, (Arg8)-vasopressin, neurotensin, ACTH1–24. Somatostatin hyperpolarized all neurons tested. Given the pronounced effects see…
Exocrine pancreatic function in children with coeliac disease before and after a gluten free diet.
1991
This study was designed to determine the extent of pancreatic insufficiency in untreated coeliac disease and whether pancreatic secretion is impaired after a prolonged gluten free period. Three groups of patients were studied: group A comprised 44 patients, mean (SD) age 4.0 (3.1) years, with coeliac disease and total or subtotal atrophy of the intestinal mucosa; group B comprised 67 patients, mean age 4.4 (3.0) years, with coeliac disease but with normal morphology of the intestinal villi (after 12.9 months of a gluten free diet); group C comprised 49 control subjects, mean age 3.2 (3.0) years, with normal jejunal histology. In all subjects exocrine pancreatic function was determined by th…

Simultaneous appearance of leukemoid reaction and phlegmasia cerulea dolens
2012
A leukemoid reaction is an extreme form of reactive leukocytosis defined as granulocytic leukocytosis above 50 × 109/L produced by normal bone marrow, mostly in response to systemic infection or cancer. The mechanism as to how the haematopoetic system is altered to elevate production of myeloid cells is not known. A 69-year-old man presented with phlegmasia cerulea dolens caused by massive iliofemoral thrombosis. His workout at admission revealed absolute white blood cell count of 73.4 × 109/L, with neutrophil granulocyte of 68.5 × 109/L. The new increase in white blood cell count happened at day 5 after admission, when the haematoma of the anteromedial thigh was evacuated in general anaes…
Increased muscle sympathetic nerve activity and impaired baroreflex control in isolated REM-sleep behavior disorder.
2021
Changes in baroreflex sensitivity have been reported in patients with idiopathic Parkinson's disease (PD). We sought to investigate the hypothesis that patients with isolated rapid eye movement (REM)-sleep behavior disorder (iRBD), known to be a prodromal stage for PD, will show abnormalities in baroreflex control.Ten iRBD patients were compared to 10 sex- and age-matched healthy controls. Their cardiovascular parameters and muscle sympathetic nerve activity (MSNA) were evaluated at rest and during baroreflex stimulation.MSNA at rest was higher in iRBD patients (burst frequency [BF]: 44 ± 3 bursts/min; burst incidence [BI]: 60 ± 8 bursts/100 heartbeats) as compared to the controls (BF: 29 ±…
Pancreatic insufficiency in celiac disease is not dependent on nutritional status
1994
To determine the relationship between pancreatic secretory capacity and nutritional status in celiac patients, we studied 52 patients with celiac disease (24 males, 28 females; age range 6-36 months) and 30 healthy control subjects (14 males, 16 females; age range 6-42 months). A secretin-cerulein test was performed on all patients, and levels of serum albumin and plasma fibronectin were assayed. In addition, weight/height ratios were calculated in the celiacs, who were then divided into three groups on this basis, as follows: celiacs with weight/height ratioor = 3rd percentile; those with weight/height ratio between the 4th and 10th percentiles; and those with weight/height ratio10th perce…
A possible tool for the choice of building materials: the environmental product declaration (EPD)
2019
The paper, contribution to the international debate on the environmental matter, deals with a tool that can guide professionals and the users in choosing low environmental impact building materials with similar functional requirements, the Environmental Product Declaration (EPD) or Type III Environmental Label, by highlighting strengths and limitations. The paper, besides describing the characteristics and contents of the EPDs and Product Category Rules (PCR), lists the main European EPD Programmes, analyzing two EPDs models in order to verify the comparability of the listed LCA data.
Recently published line strengths for the transition array 3s–3p in C I, N II and O III: a critical review
2014
Recently calculated atomic structure data for C I, N II and O III are reviewed and analyzed by performing J-file sum rule tests. The line strengths of the 3s–3p transition array are analyzed. In the case of neutral carbon and ionized nitrogen data, the LS-forbidden transitions are included in the analysis.
