Occupational Goal Intervention Method for the Management of Executive Dysfunction in People With Treatment-Resistant Schizophrenia: A Randomized Controlled Trial.

Importance: The occupational goal intervention (OGI) method has been proven effective in improving executive function (EF) in people with schizophrenia, but it has not yet been tested with those with treatment-resistant schizophrenia (TRS).

Objective: To test the efficacy of the OGI in people with TRS.

Design: Single-blind randomized controlled trial.

Granzyme B Produced by Natural Killer Cells Enhances Inflammatory Response and Contributes to the Immunopathology of Cutaneous Leishmaniasis.

Background: Skin lesions from patients infected with Leishmania braziliensis has been associated with inflammation induced by cytotoxic CD8+ T cells. In addition, CD8+ T cell-mediated cytotoxicity has not been linked to parasite killing. Meanwhile, the cytotoxic role played by natural killer (NK) cells in cutaneous leishmaniasis (CL) remains poorly understood.

Agroforestry coffee soils increase the insect-suppressive potential offered by entomopathogenic fungi over full-sun soils: A case proposing a "bait survival technique".

Entomopathogenic fungi are important natural enemies of insects. However, there is little information on the insect-suppressive potential of these fungi and possible effects of farming management on this. Meanwhile, changes in natural landscapes due to agricultural intensification have caused considerable biodiversity loss and consequent decay of ecosystem services.

A pilot randomized controlled trial of the Occupational Goal Intervention method for the improvement of executive functioning in patients with treatment-resistant schizophrenia.

Schizophrenia is a chronic disabling mental disorder that involves impairments in several cognitive domains, especially in executive functions (EF), as well as impairments in functional performance. This is particularly true in patients with Treatment-Resistant Schizophrenia (TRS). The aim of this study was to test the efficacy of the Occupational Goal Intervention (OGI) method for the improvement of EF in patients with TRS.

Nonpharmacological Interventions to Reduce Behavioral and Psychological Symptoms of Dementia: A Systematic Review.

Introduction: Behavioral and psychological symptoms of dementia (BPSD) are defined as a group of symptoms of disturbed perceptive thought content, mood, or behavior that include agitation, depression, apathy, repetitive questioning, psychosis, aggression, sleep problems, and wandering. Care of patients with BPSD involves pharmacological and nonpharmacological interventions. We reviewed studies of nonpharmacological interventions published in the last 10 years.

Clinical and immunological outcome in cutaneous leishmaniasis patients treated with pentoxifylline.

Pentoxifylline is a tumor necrosis factor-α (TNF-α) inhibitor that also attenuates the immune response and decreases tissue inflammation. The association of pentoxifylline with antimony improves the cure rate of mucosal and cutaneous leishmaniasis. In this randomized and double blind pilot trial, cure rate was higher, although not significant, in patients who received antimony plus pentoxifylline than in those patients receiving antimony plus placebo.

In vitro effects of acute amiodarone and dronedarone on epicardial, endocardial, and M cells of the canine ventricle.

Amiodarone (AM) is an antiarrhythmic agent widely used in the treatment of ventricular and supraventricular arrhythmias. Dronedarone (DR) is a new compound with a pharmacological profile similar to that of AM, but iodine free. We previously demonstrated that chronic AM treatment reduces transmural dispersion of repolarization (TDR) in the canine heart.

Acute in vitro effects of dronedarone, an iodine-free derivative, and amiodarone, on the rabbit sinoatrial node automaticity: a comparative study.

Amiodarone is a potent antiarrhythmic drug commonly used in the treatment of supraventricular and ventricular arrhythmias. Dronedarone is a recently developed iodine-free compound (Sanofi Recherche), structurally related to amiodarone. Amiodarone and dronedarone have shown similar long-term effects on sinoatrial node automaticity in vivo and in vitro in the rabbit heart.

Anti-endothelial antibodies and neuropsychiatric systemic lupus erythematosus.

The pathogenesis of neuropsychiatric systemic lupus erythematosus (NPSLE) has been attributed to autoantibody-mediated neural dysfunction, vasculopathy, and coagulopathy. Several autoantibodies specificities have been reported in serum and cerebrospinal fluid of NPSLE patients (i.e.

[Soluble P-selectin levels in synovial fluid and serum from patients with psoriatic arthritis].

Objective: P-selectin is an adhesion molecule expressed by activated endothelial cells and platelets favouring the leukocyte adherence to microvascular endothelium. A soluble form of this molecule has been described, whose serum levels were found to be elevated and correlate with disease activity in rheumatoid arthritis (RA) patients. Aim of this study was to determine soluble P-selectin levels in synovial fluid (SF) and serum from patients with psoriatic arthritis (PsA), where it has never been investigated, to define its involvement in PsA synovial damage.

Ménière's disease and anxiety disorders.

Diagnosis of Menière's Disease is based upon the wellknown labyrinthic syndrome (hypoacusia, tinnitus and dizziness) which manifests with the typical abscessual, recurrent and unforeseeable course. Many Menière patients also report panic attacks, agoraphobia and anxiety which make evaluation of labyrinthic symptoms difficult, affect the onset and maintenance of vestibular compensation and require specific treatments which are very different from those for the control of endolymphatic hydrops. In order to analyse the nature and the meaning of the association of the vestibular and psychiatric symptoms, a comparison has been made between patients presenting Menière's disease, and a group of patients with dizziness resulting from other vestibular diseases.

Allergic rhinitis in Italy: epidemiology and definition of most commonly used diagnostic and therapeutic modalities.

Allergic rhinitis is classically defined as an IgE-mediated inflammation of nasal mucosa, characterised by nasal obstruction, rhinorrhea, sneezing and nasal itching. It is certainly a high-prevalence disease and an important social and medical problem in many industrialised Countries, affecting about 20% of the general population; moreover, it is diagnosed with increasing frequency, both in adults and children in many developing countries. In view of the high medical and social costs, a correct diagnostic approach to allergic rhinitis is a fundamental need for the otorhinolaryngologist, also considering the severe complications (asthma, rhinosinusitis, rhino-otitis, rhinosinusal polyposis) which could develop if this disease is not recognised and adequately treated in its early phases.

CD34-positive cells in human umbilical cord blood express nerve growth factor and its specific receptor TrkA.

In this study, we investigated whether hematopoietic stem cells (HSC) and progenitors present in human cord blood can express nerve growth factor (NGF)-specific receptors, TrkA and p75. Our results showed a marked expression of TrkA and NGF in cord blood CD34(+) cells. A gradient of TrkA and NGF expression exists and is highest in cord blood CD34(+) cells, reduced in cord blood mononuclear cells (MNC) and minimal in mononuclear cells isolated from adult peripheral blood.

Hepatitis C virus infection of salivary gland epithelial cells. Lack of evidence.

Background: Hepatitis C virus genome (HCV-RNA) has been detected in whole salivary gland tissue of chronically infected patients. However, contamination of the tissue by plasma or blood cells was not excluded by the previous reports.

Aims: To assess whether HCV infects the salivary gland epithelial cells in patients with chronic HCV liver disease.

[Initial symptoms in Meniere's disease].

Menière's disease appears with the classic triad of symptoms in about 1/3 of cases so that, on the whole, diagnosis is delayed until full symptomatology develops. Spontaneous reversibility and effective control, if any, of the disease mechanism are limited to the beginning phases and thus it seems appropriate focus attention on the earliest symptoms. Unfortunately, the pre-diagnosis period is poorly known and, for this reason, we decided to investigate it in our series.

[Recovery from Meniere's disease].

When vertigo attacks and balance disorders stop, menieric patients are generally considered recovered although they complain of more or less severe sensorineural hearing loss. As far as a true clinical recovery is concerned, the Authors think that it should correspond not only to absence of vertiginous spells but even to a long lasting normal and stable hearing level. On the basics of this presumption, they select the files of 7/207 patients showing complete recovery since not less than 8 years.

Hepatitis C virus infection in chronic liver disease in Somalia.

To assess the role of hepatitis C virus (HCV) in liver disease in Somalia, antibody to HCV (anti-HCV) was studied by enzyme-linked immunosorbent assay (ELISA) and recombinant immunoblot assay (RIBA) in 110 patients with chronic liver diseases, in 309 healthy adults, in 179 institutionalized subjects with a high prevalence of intestinal parasites and Schistosoma haematobium, and in 287 children with diseases other than hepatitis. According to the RIBA test, anti-HCV was present in three healthy adults (0.97%), in four institutionalized individuals (2.

IgG subclasses in human hydatid disease: prominence of the IgG4 response.

To assess the participation of the four subclasses of IgG in the humoral response to Echinococcus granulosus infection, we determined total and parasite-specific IgG1, IgG2, IgG3 and IgG4 in sera from 46 patients with hydatid disease using an enzyme-linked immunosorbent assay (ELISA). Parasite-specific IgG subclass antibodies were quantitatively measured by means of standard curves obtained by affinity chromatography. Sera from 35 healthy individuals served as controls.

[The circulation of the hepatitis A and B viruses in the Somali population].

We report the results of a study carried out to evaluate the extent of hepatitis A virus (HAV) and hepatitis B virus (HBV) circulation in Somalia. Serum samples were collected from 593 subjects (age range 0-83 years) and tested for anti-hepatitis A (HAV) and anti-HAV IgM. Serum samples taken from 1272 individuals (age range 0-83 years) were tested for HBsAg, anti-HBsAg, anti-HBcAg, HBeAg and anti-HBeAg.

Spontaneous in vitro generation of histamine releasing factor from mononuclear cells of patients with hydatidosis.

We have shown that Echinococcus granulosus infection can induce an enhanced sensitivity of basophils to IgE-dependent stimuli. To determine whether a cytokine, histamine releasing factor, could account for it, we evaluated 35 patients with active hydatidosis, 5 patients with past E. granulosus infection, and 20 normal volunteers.
