[Drugs use in pregnancy in the Valencia Region and the risk of congenital anomalies].
2017
Background Despite the potential risks of drug use during pregnancy, consumption has increased in recent decades. Objective To identify the risk of congenital anomalies (CA) associated with the use of drugs in primary care in pregnant women resident in the Valencia Region. Methods A case-control study, considering a case as a less than one year old live birth in 2009–2010, diagnosed with a CA and resident in the Valencia Region, obtained from the CA population-based registry. Controls were selected from the Metabolic Disease Registry, and the drugs prescribed and dispensed from the Integral Management of Pharmaceutical Services. Crude odds ratio (OR) was calculated with its 95% confidence i…
Hepatitis E Virus Detection in Liver Tissue from Patients with Suspected Drug-Induced Liver Injury
2015
Hepatitis E virus (HEV) infection is increasingly recognized as a cause of acute hepatitis in the industrialized world. We aimed to determine the frequency of acute Hepatitis E virus (HEV) infection in cases of suspected drug-induced liver injury (DILI), mainly a diagnosis of exclusion. To this aim, formalin-fixed, paraffin-embedded (FFPE) liver tissues of all cases routinely processed in our institute during a 2 ½ years period in which DILI was amongst the differential diagnoses (157 liver biopsies, one liver explant) were subjected to semi-nested RT-PCR for the detection of hepatitis E virus (HEV) RNA. Histopathology was re-evaluated on all cases tested positive. HEV RNA was detectable in…
Impact of medications on salivary flow rate in patients with xerostomia: a retrospective study by the Xeromeds Consortium
2022
OBJECTIVES: This study evaluates the impact of systemic medications and polypharmacy on unstimulated (UWS) and chewing-stimulated whole saliva (SWS) flow rates in patients with xerostomia.MATERIAL AND METHODS: This cross-sectional multicenter study is based on data of patients referred to five oral medicine outpatient practices in Europe and USA from January 2000 and April 2014. Relevant demographic, social, medical history and current medications were collected.RESULTS: The study included 1144 patients, 972 (85%) females, with a mean (SD) age of 59 (14.1) years. In unmatched patients, the UWS flow rate was lower in patients taking a medication (vs. not taking a medication) from the followi…
Cytometric analysis for drug-induced steatosis in HepG2 cells
2009
Drugs are capable of inducing hepatic lipid accumulation. When fat accumulates, lipids are primarily stored as triglycerides which results in steatosis and provides substrates for lipid peroxidation. An in vitro multiparametric flow cytometry assay was performed in HepG2 cells by using fluorescent probes to analyze cell viability (propidium iodide, PI), lipid accumulation (BODIPY493/503), mitochondrial membrane potential (tetramethyl rhodamine methyl ester, TMRM) and reactive oxygen species generation (ROS) (2',7'-dihydrochlorofluorescein diacetate, DHCF-DA) as functional markers. All the measurements were restricted to live cells by gating the cells that excluded PI or those that exhibited…
Cerebellar magnetic stimulation decreases levodopa-induced dyskinesias in Parkinson disease
2009
BACKGROUND: The neural mechanisms and the circuitry involved in levodopa-induced dyskinesia (LID) are still partially obscure. LID can be considered the consequence of an abnormal pattern or code of activity that originates and is conveyed from the basal ganglia to the thalamus and the cortical motor areas. However, not only striatothalamocortical motor circuits but also other interconnected pathways could be implicated in its pathogenesis. METHODS: In a series of experiments, we applied repetitive transcranial magnetic stimulation (rTMS) over the lateral cerebellum in a group of patients with advanced Parkinson disease, to investigate whether modulation of cerebellothalamocortical circuits…
Both Short- and Long-Acting D-1/D-2 Dopamine Agonists Induce Less Dyskinesia than l-DOPA in the MPTP-Lesioned Common Marmoset (Callithrix jacchus)
2002
Abstract The current concept of dyskinesia is that pulsatile stimulation of D-1 or D-2 receptors by l -DOPA or short-acting dopamine agonists is more likely to induce dyskinesia compared to long-acting drugs producing more continuous receptor stimulation. We now investigate the ability of two mixed D-1/D-2 agonists, namely pergolide (long-acting) and apomorphine (short-acting), to induce dyskinesia in drug-naive MPTP-lesioned primates, compared to l -DOPA. Adult common marmosets ( Callithrix jacchus ) were lesioned with MPTP (2 mg/kg/day sc for 5 days) and subsequently treated with equieffective antiparkinsonian doses of l -DOPA, apomorphine, or pergolide for 28 days. l -DOPA, apomorphine, …
EFFECT OF THE IMPase INHIBITOR L690,330 ON SEA URCHIN DEVELOPMENT
1998
Abstract A variety of concentrations of the IMPase inhibitor L690,330 were added to sea urchin embryos. Immediate arrest of development was obtained for concentrations from 7.5 m m on. Concentrations lower than 3.5 m m permitted gastrulation but inhibited skeletogenesis and disturbed elongation along the animal–vegetal axis. The latter results are similar to those obtained by counteracting lithium effect with myoinositol, which are suggested to be due to partial relief of IMPase inhibition.
Dydrogesterone use during pregnancy: Overview of birth defects reported since 1977
2009
Between 1977 and 2005, 28 cases of potential links between maternal dydrogesterone use during pregnancy and congenital birth defects were reported. The types of defects were very diverse, with no evidence of a pattern of abnormalities. The data do not provide evidence for congenital malformations associated with dydrogesterone use.
Toxicity of lindane, atrazine, and deltamethrin to early life stages of zebrafish (Brachydanio rerio).
1990
Fertilized eggs of zebrafish were exposed under flow-through conditions to several concentrations of the following pesticides: lindane 40, 80, 110, 130, and 150 micrograms/liter; atrazine 300, 1300, and 9100 micrograms/liter; deltamethrin 0.5, 0.8, and 1.2 micrograms/liter. Hatching, abnormalities in development (external deformations, edema, etc.), and mortality were recorded over a period of 35 days. At the end of the experiment, the body lengths of the fish were measured. Survival of juvenile fish after 35 days was reduced by increasing concentrations of all xenobiotics tested: lindane enhanced the mortality from 110 micrograms/liter and atrazine from 1300 micrograms/liter, and deltameth…
Cognitive impairment and levodopa induced dyskinesia in Parkinson’s disease: a longitudinal study from the PACOS cohort
2021
AbstractAim of the study was to evaluate possible associations between cognitive dysfunctions and development of Levodopa Induced Dyskinesia (LID). PD patients from the Parkinson’s disease Cognitive impairment Study cohort who underwent a baseline and follow-up neuropsychological evaluations were enrolled. Mild Cognitive Impairment (PD-MCI) was diagnosed according to MDS level II criteria. The following cognitive domains were evaluated: episodic memory, attention, executive function, visuo-spatial function and language. A domain was considered as impaired when the subject scored 2 standard deviation below normality cut-off values in at least one test for each domain. Levodopa equivalent dos…
