Protocollo di campionamento della fauna ittica nei laghi italiani

Abstract not availableIl presente documento definisce le modalit? per il campionamento della fauna ittica in ambienti lacustri finalizzato alla valutazione dello stato ecologico di un lago in linea con le richieste della Direttiva 2000/60/CE (European Union 2000). Il protocollo definisce un metodo standard per il campionamento della fauna ittica finalizzato alla raccolta dei dati necessari per valutare la composizione, abbondanze e struttura di popolazione della comunit? ittica in un ambiente lacustre. Il protocollo si basa sui documenti UNI EN di riferimento a livello Europeo (UNI EN 14757; UNI EN 14962)

Hyposplenism as a cause of pneumococcal meningoencephalitis in an adult patient with coeliac disease

Introduction: Coeliac disease can be associated with hyposplenism and splenic atrophy, which may increase the patient's risk for fatal infections caused by Streptococcus pneumoniae or Pneumococcus. It is general opinion that many more patients with coeliac disease have died from hyposplenism-related infections than those reported in literature. Case report: A 62-year-old woman with recently diagnosed coeliac disease was hospitalized with high fever, disorientation, and nuchal rigidity. Cerebral computed tomography was negative. Laboratory tests showed an elevated leukocyte count and very high levels of C reactive protein. The cerebrospinal fluid (CSF) contained an increased number of mononuclear cells associated with a low glucose level and high protein concentrations. The CSF culture was positive for Streptococcus pneumoniae. Neurological conditions rapidly deteriorated with the onset of coma, and magnetic resonance imaging of the brain revealed initial signs of encephalitis extending above and below the tentorium. Abdominal ultrasonography disclosed splenic hypotrophy that raised the suspicion of hyposplenism. The diagnosis of hyposplenism was confirmed by demonstration of Howell-Jolly bodies in a peripheral blood smear. Discussion: This is the first reported case of pneumococcal meningoencephalitis caused by splenic hypofunction in a patient with coeliac disease. When coeliac disease is diagnosed with a marked delay in an elderly patient, spleen function should always be assessed. If impaired, the patient should undergo vaccination with pneumococcal conjugate vaccine to prevent pneumococcal infections

Early Occupational Therapy Intervention: Patients’ Occupational Needs

The occupational therapy management involves the assessment of the individual’s specific needs. This kind of assessment facilitates the therapeutic relationship and boosts the person’s motivation, as he or she feels valued and heard. Early-stage collection of information about meaningful activities for the individual helps them project themselves outside the context of illness. Collecting occupational need at an early stage, permits “Engagement”, which means participating in activities even without actually doing them. An occupational therapy model called “Personal Environment Occupation Model” suggests that already at an early stage we should make the environment and occupations meaningful to the person in order to maximise the patient’s performance. An observational study on stroke patients shows how people have personal occupational needs beyond simple self-care, including productive life and leisure time, already in the subacute phase. A further study is underway to demonstrate the effectiveness of early occupational therapy intervention, including complex patients regardless of diagnosis and taking into account their need for care and disability in order to promote their participation and maximise their autonomy

Responses of peripheral blood mononucleated cells from non-celiac gluten sensitive patients to various cereal sources

Non-celiac gluten sensitivity (NCGS) is still an undefined syndrome whose triggering mechanisms remain unsettled. This study aimed to clarify how cultured peripheral blood mononucleated cells (PBMC) obtained from NCGS patients responded to contact with wheat proteins. Results demonstrated that wheat protein induced an overactivation of the proinflammatory chemokine CXCL10 in PBMC from NCGS patients, and that the overactivation level depends on the cereal source from which proteins are obtained. CXCL10 is able to decrease the transepithelial resistance of monolayers of normal colonocytes (NCM 460) by diminishing the mRNA expression of cadherin-1 (CDH1) and tight junction protein 2 (TJP2), two primary components of the tight junction strands. Thus, CXCL10 overactivation is one of the mechanisms triggered by wheat proteins in PBMC obtained from NCGS patients. This mechanism is activated to a greater extent by proteins from modern with respect to those extracted from ancient wheat genotypes

Mutations in RAD21 disrupt regulation of apob in patients with chronic intestinal pseudo-obstruction

Background Aims Chronic intestinal pseudo-obstruction (CIPO) is characterized by severe intestinal dysmotility that mimics a mechanical subocclusion with no evidence of gut obstruction. We searched for genetic variants associated with CIPO to increase our understanding of its pathogenesis and to identify potential biomarkers. Methods We performed whole-exome sequencing of genomic DNA from patients with familial CIPO syndrome. Blood and lymphoblastoid cells were collected from patients and controls (individuals without CIPO); levels of messenger RNA (mRNA) and proteins were analyzed by quantitative reverse-transcription polymerase chain reaction, immunoblot, and mobility shift assays. Complementary DNAs were transfected into HEK293 cells. Expression of rad21 was suppressed in zebrafish embryos using a splice-blocking morpholino (rad21a). Gut tissues were collected and analyzed. Results We identified a homozygous mutation (p.622, encodes Ala>Thr) in RAD21 in patients from a consanguineous family with CIPO. Expression of RUNX1, a target of RAD21, was reduced in cells from patients with CIPO compared with controls. In zebrafish, suppression of rad21a reduced expression of runx1; this phenotype was corrected by injection of human RAD21 mRNA, but not with the mRNA from the mutated p.622 allele. rad21a Morpholino zebrafish had delayed intestinal transit and greatly reduced numbers of enteric neurons, similar to patients with CIPO. This defect was greater in zebrafish with suppressed expression of ret and rad21, indicating their interaction in the regulation of gut neurogenesis. The promoter region of APOB bound RAD21 but not RAD21 p.622 Ala>Thr; expression of wild-type RAD21 in HEK293 cells repressed expression of APOB, compared with control vector. The gut-specific isoform of APOB (APOB48) is overexpressed in sera from patients with CIPO who carry the RAD21 mutation. APOB48 also is overexpressed in sporadic CIPO in sera and gut biopsy specimens. Conclusions Some patients with CIPO carry mutations in RAD21 that disrupt the ability of its product to regulate genes such as RUNX1 and APOB. Reduced expression of rad21 in zebrafish, and dysregulation of these target genes, disrupts intestinal transit and the development of enteric neurons. © 2015 by the AGA Institute
