A Randomized Controlled Trial of Continuous Positive Airway Pressure on Glucose Tolerance in Obese Patients with Obstructive Sleep Apnea

2014

Study objectives Obstructive sleep apnea (OSA) is associated with an increased prevalence of metabolic syndrome (MetS), even in patients with morbid obesity. Our goal was to address whether continuous positive airway pressure (CPAP) treatment improved glucose metabolism in this population. Methods A prospective randomized controlled trial was performed in severe OSA patients with morbid obesity without diabetes in two university referral hospitals. Patients received conservative (CT) versus CPAP treatment for 12 weeks. MetS components, homeostasis model assessment of insulin resistance (HOMA-IR) and oral glucose tolerance were assessed at baseline and after treatment. Results A total of 80 …

Results of an Open Clinical Trial of Brofaromine (CGP 11 305 A), a Competitive, Selective, and Short-Acting Inhibitor of MAO-A in Major Endogenous De…

1987

In an open clinical trial the authors treated 18 hospitalized patients suffering from endogenous depression with brofaromine (CGP 11305A), a competitive, selective, and short-acting inhibitor of type A monoamine oxidase (MAO). Four patients were defined as good responders, as they had a final HAMD score of between 0 and 7 points. Four patients were judged as improved, with final HAMD scores of between 8 and 15 points, while the remaining eight patients failed to respond (final HAMD score greater than or equal to 16 points). The major observations were a beneficial influence on drive in most patients, while paranoid symptoms worsened markedly, rendering the substance contraindicated in psych…

Anatomical correlates of ocular motor deficits in cerebellar lesions

2009

Humans are able to stabilize the images of moving targets on the retina by means of smooth pursuit eye movements. After the pontine level, all smooth pursuit pathways pass through the cerebellum. Previous animal studies gave evidence that two specific lesion sites within the cerebellum cause smooth pursuit disorders: those of the flocculus/paraflocculus and the vermis including lobule VI, VII, the uvula and the deep cerebellar nuclei. To date, there have been only a few lesion studies in patients with smooth pursuit disorders that do not allow direct comparison with a control group. In the present study, new lesion mapping techniques determined which cerebellar structures were involved in p…

Active immunization of homosexual men using a recombinant hepatitis B vaccine

1989

Twenty homosexual men [13 anti-human immunodeficiency virus (HIV)-positive, seven anti-HIV negative] without HBsAg, anti-HBs, and anti-HBc were vaccinated with three 20 micrograms doses of a recombinant hepatitis B vaccine. All anti-HIV-positive homosexuals were nonresponders independent of the initial number of CD4-positive cells. Among seven anti-HIV-negative individuals, five responded. After three doses of the vaccine, CD4-positive cells fell in anti-HIV positive individuals by 22.4%. A similar fall in CD4-positive cells of an average 24.9% was noted in 17 matching, but nonvaccinated, anti-HIV-positive homosexuals. The study indicates that the efficacy of vaccination in anti-HIV-positiv…

PSA-NCAM expression in the human prefrontal cortex.

2006

The prefrontal cortex (PFC) of adult rodents is capable of undergoing neuronal remodeling and neuroimaging studies in humans have revealed that the structure of this region also appears affected in different psychiatric disorders. However, the cellular mechanisms underlying this plasticity are still unclear. The polysialylated form of the neural cell adhesion molecule (PSA-NCAM) may mediate these structural changes through its anti-adhesive properties. PSA-NCAM participates in neurite outgrowth and synaptogenesis and changes in its expression occur parallel to neuronal remodeling in certain regions of the adult brain. PSA-NCAM is expressed in the hippocampus and temporal cortex of adult hum…

CD1a-positive infiltrating-dendritic cell density and 5-year survival from human breast cancer.

2003

Infiltrating CD1a(+) dendritic cells (DCs) have been associated with increased survival in a number of human cancers. This study investigated DC infiltration within breast cancers and the association with survival. Classical established prognostic factors, of tumour size, lymph node status, histological grade, lympho-vascular invasion, the KI-67 (MIB-1) fraction and the Nottingham Prognostic Index (NPI) were also compared. A total of 48 breast cancer patients were followed from the time of surgery and CD1a density analysis for 5 years or until death. Our data set validated previous studies, which show a relationship between survival and the NPI (P0.001), tumour size (P0.01) and lymph node s…

Lack of association of a functional catechol-O-methyltransferase gene polymorphism with risk of tobacco smoking: results from a multicenter case-cont…

2013

Background The catechol-O-methyltransferase (COMT) modulates dopaminergic neurotransmission in the prefrontal cortex as well as in the mesolimbic reward system. Since the reward system mediates addictive behavior, the COMT gene is a strong candidate gene regarding the pathophysiology of tobacco dependence and smoking behavior. Because of rather conflicting results in previous studies, the purpose of the present study was to test for association between a functional genetic variant in the COMT gene (single nucleotide polymorphism [SNP] rs4680) and tobacco smoking behavior. Methods In a population-based case-control multicenter study designed for tobacco addiction research, a total of 551 cur…

Three de novo losses and one insertion within a pericentric inversion of chromosome 6 in a patient with complete absence of expressive speech and red…

2008

A 32-year-old female patient, observed for 30 years because of a distinctive phenotype consisting of a dysmorphic face non-progressive deficit of motor control, lack of speech development, reduced sensitivity to pain, with a known, complex interstitial deletion 6q14 within a de novo pericentric inversion 6p11.2;q15, was re-examined at the molecular level. Applying the Infinium HumanHap300 BeadChip array and BAC-based FISH we found two new non-contiguous microdeletions in addition to the one detected previously by high resolution G-band analysis. A 360 kb loss in band 6p12.3, containing the genes RHAG, CRISP1, 2, and 3, and PGK2, a 1.15 Mb loss in 6p12.2-p12.1, containing the genes PKHD1, IL…

Neurochemical alterations in women with borderline personality disorder and comorbid attention-deficit hyperactivity disorder

2010

Borderline personality disorder (BPD) is associated with structural and functional brain changes. Recent models and findings refer to alterations of glutamate and total N-acetylaspartate (tNAA) in this condition.Absolute quantities of tNAA, creatine, glutamate, glutamine, myoinositol and total choline were measured using 3 Tesla magnetic resonance spectroscopy of the left anterior cingulate cortex and the left cerebellum in 14 unmedicated women with BPD and comorbid attention-deficit hyperactivity disorder (ADHD) and 18 healthy women. Both groups were matched with respect to age, education and premorbid intelligence.In the anterior cingulate, we found significantly higher tNAA and glutamate…
