RESUMO
Background: In literature there is a lack of specific evaluation tools for behavior in intellectual disabilities in general and during an activity, this is one of the most important field of the Occupational Therapy intervention. Objective: Authors developed an Italian version of the Occupational Therapy Task Observation Scale (OTTOS) and an Italian version of the Comprehensive Occupational Therapy Evaluation Scale (COTES) and examined their reliability and validity. Methods: The original scales were translated from English to Italian using the "Translation and Cultural Adaptation of Patient Reported Outcomes Measures-Principles of Good Practice" guidelines. Both scales were administered to adults with mild and moderate intellectual disabilities. People under eighteen years, with severe and profound intellectual disabilities and deaf people were excluded from the study. Their reliability and validity have been examined. Relia-bility was analyzed via internal consistency (Cronbach's alpha) and stability (intra/inter-rater coefficient), while validity was investigated via construct validity (p-value) and criterion validity using Pearson's correlation coefficients between them and with the Mini Mental State Examination and the Barthel Index Scale. Results: The OTTOS and the COTES were administered to 30 subjects. Cronbach's α for the COTES was 0,91 and Cronbach's α for the OTTOS was 0,92. Regarding the criterion of validity, the two scales have numerous statistically positive correlations, particularly with the Mini Mental State Examination in the Orientation and total part. Furthermore, the correlation with the Barthel scale is present in the total scores, the COTES's third subscale, and the OTTOS's first. Conclusions: The OTTOS and the COTES were reliable and valid outcome measures for assessing behavior in the Italian population.

In the context of widespread loss, isolation, and grief due to COVID-19, palliative social workers came together in the fall of 2020 to form an international group named the World Hospice and Palliative Care Social Work Network (WHPCSW). This emerging global network is committed to amplifying the innovative work, nuanced skills, research, and education and training provided by palliative social workers across different settings around the world. This article highlights some of the novel interventions developed by social workers in response to the pandemic and describes this coalescing WHPCSW network along with information about its mission and membership.

INTRODUCTION: A multi-centre study has been conducted, during 2005, by means of a questionnaire posted on the Italian Society of Emergency Medicine (SIMEU) web page. Our intention was to carry out an organisational and functional analysis of Italian Emergency Departments (ED) in order to pick out some macro-indicators of the activities performed. Participation was good, in that 69 ED (3,285,440 admissions to emergency services) responded to the questionnaire. METHODS: The study was based on 18 questions: 3 regarding the personnel of the ED, 2 regarding organisational and functional aspects, 5 on the activity of the ED, 7 on triage and 1 on the assessment of the quality perceived by the users of the ED. RESULTS AND CONCLUSION: The replies revealed that 91.30% of the ED were equipped with data-processing software, which, in 96.83% of cases, tracked the entire itinerary of the patient. About 48,000 patients/year used the ED: 76.72% were discharged and 18.31% were hospitalised. Observation Units were active in 81.16% of the ED examined. Triage programmes were in place in 92.75% of ED: in 75.81% of these, triage was performed throughout the entire itinerary of the patient; in 16.13% it was performed only symptom-based, and in 8.06% only on-call. Of the patients arriving at the ED, 24.19% were assigned a non-urgent triage code, 60.01% a urgent code, 14.30% a emergent code and 1.49% a life-threatening code. Waiting times were: 52.39 min for non-urgent patients, 40.26 min for urgent, 12.08 for emergent, and 1.19 for life-threatening patients.

Evidence indicates that lipoxygenases (LO) may play a role in cancer cell survival. We show that human malignant pleural mesothelial (MM) cells, but not normal mesothelial (NM) cells, express a catalytically active 5-LO. Pharmacological or genetic inhibition of MM cell 5-LO determined nucleosome formation and induced a DNA fragmentation pattern typical of apoptosis. This was completely reversed by exogenously added 5(S)-HETE but not by 12(S)-, 15(S)-HETE, or leukotriene (LT)B4. A 5-LO antisense oligonucleotide potently and time-dependently reduced vascular endothelial growth factor (VEGF) mRNA and constitutive VEGF accumulation in the conditioned media of MM cells. When NM cells were transfected with a 5-LO cDNA, basal and arachidonic acid-induced VEGF formation increased consistently by 6- and 12-fold, respectively. This was associated with a significant increase in DNA synthesis that was counteracted by a specific anti-VEGF antibody. Arachidonic acid and 5(S)-HETE also potently stimulated the activity of a VEGF promoter construct. Thus, 5-LO is a key regulator of MM cell proliferation and survival via a VEGF-related circuit.

G-protein-coupled receptor kinases (GRKs) are involved in the regulation of many G-protein-coupled receptors. As opposed to the other GRKs, such as rhodopsin kinase (GRK1) or beta-adrenergic receptor kinase (beta ARK, GRK2), no receptor substrate for GRK4 has been so far identified. Here we show that GRK4 is expressed in cerebellar Purkinje cells, where it regulates mGlu(1) metabotropic glutamate receptors, as indicated by the following: 1) When coexpressed in heterologous cells (HEK293), mGlu(1) receptor signaling was desensitized by GRK4 in an agonist-dependent manner (homologous desensitization). 2) In transfected HEK293 and in cultured Purkinje cells, the exposure to glutamate agonists induced internalization of the receptor and redistribution of GRK4. There was a substantial colocalization of the receptor and kinase both under basal condition and after internalization. 3) Kinase activity was necessary for desensitizing mGlu(1a) receptor and agonist-dependent phosphorylation of this receptor was also documented. 4) Antisense treatment of cultured Purkinje cells, which significantly reduced the levels of GRK4 expression, induced a marked modification of the mGlu(1)-mediated functional response, consistent with an impaired receptor desensitization. The critical role for GRK4 in regulating mGlu(1) receptors implicates a major involvement of this kinase in the physiology of Purkinje cell and in motor learning.

In this study, we investigated the regulation of different G protein-coupled receptor (GPCR)-stimulated signaling pathways by GPCR kinase 2 (GRK2). We used thyrotropin receptor, which is coupled to different G proteins, to investigate the regulation of Galphas- and Galphaq-mediated signaling (assessed by cAMP and inositol phosphate production, respectively). In transfected cells, both pathways were desensitized by GRK2. However a kinase-dead GRK2 mutant (GRK2-K220R) only decreased inositol phosphate production, indicating that GRK2 could regulate Galphaq signaling through a phosphorylation-independent mechanism. Similar results were obtained with serotonin receptor 5-hydroxytryptamine(2C), which is coupled to Galphaq. This effect was mimicked by the N-terminal domain of GRK2 (GRK2-Nter), but not by the C-terminal domain. In cells transfected with Galphaq, direct activation of Galphaq signaling (by AlF(4)(-)) was desensitized by GRK2-Nter, indicating an effect at the Galpha-level. For comparison, in parallel samples we studied a protein regulator of G protein signaling RGS4 and we found a similar regulatory profile. We therefore hypothesized that the GRK2-Nter could directly interact with the Galphaq subunit to regulate its signaling, as demonstrated for several RGS proteins. This hypothesis is further supported by the presence, within the GRK2-Nter, of an RGS homology domain. In direct binding experiments, we found that GRK2-Nter interacts with Galphaq (only when activated) but not with Galphas and Galphao. We conclude that GRK2, besides desensitizing the GPCR by phosphorylation, is able to selectively bind to Galphaq and to regulate its signaling.

171 cases consecutively seen in a hospital emergency service were prospectively evaluated. Several data were recorded to assess the type of care given and the need for attention in an institution with the technical resources of a hospital. These data were evaluated considering whether the user had moved from another town to receive attention and whether he had been referred by a physician or not. There were definite differences in the behavior of the user from the town where the hospital is located and the remaining users. These differences were not attributable to a different performance or evaluation from the primary care services of the several towns involved. It was concluded that, at the present time, the use of the emergency service of our hospital is significantly influenced by the decision of the user to consult the service. Factors other than the severity of the disease influence this decision.
