RESUMO

The demographic projections on the European population predict that people aged over 60 will increase by about two million/year in the next decades. Since 2012, the Campania Reference Site of the European Innovation Partnership on Active and Healthy Ageing supports the innovation of the Regional Health System, to face up demographic changes and sustainability. Campania Reference Site provides the opportunity to connect loco-regional stakeholders in social and health care services (universities, healthcare providers, social services, local communities and municipalities), with international organizations, in order to adopt and scale up innovative solutions and approaches. This paper describes the building process of Campania Reference Site and the main results achieved, that have been allowing it to become a hub for open innovation in the field of active and healthy aging at regional, national and international level.

RESUMO

BACKGROUND: In the last years, patients' empowerment has been increasingly recognized as a crucial dimension of patient-centered healthcare and patient safety. Nevertheless, little work has been done so far in the field of patient safety to investigate strategies for empowering psychiatric patients. Therefore, the aim of this study was to identify, by using focus groups, whether and how psychiatric patients' empowerment can improve risk management according to the perspective of healthcare providers (HPs). METHODS: A mixed-method approach composed of a qualitative data collection method (i.e., focus groups) and a quantitative analysis technique (i.e., inductive content analysis) was applied. HPs working in mental health settings shared their perspectives on psychiatric patients' empowerment in risk management. After the transcription of the audio-taped discussions and the subsequent development of a hierarchical four-level coding system (strategy versus critical issue, thematic area, category, subcategory), two independent raters codified the transcripts and synthesized the content. Absolute frequencies are reported for quantitative data. RESULTS: Twelve focus groups consisting of six to ten participants, each with an overall sample size of 95 participants (65 women; average age ± SD 47 ± 9 yrs), were enrolled. A total of 1252 participants' verbal contributions (i.e., units of analysis) were assessed. Strategies and critical issues (Level 1) were mentioned almost equally (52 and 48%, respectively) by the HPs. Most of the contributions at Level 2 referred to the thematic areas Treatment and Cure (69%) and Emergency Management (21%). In the area Treatment and Cure, the category Therapeutic Compliance (Level 3) was discussed in one third of all contributions. CONCLUSIONS: Our results suggest that HPs consider patients as crucial partners in risk management and expect them to play a key role in actively enhancing safety. Policy makers should be aware that risk management in mental health settings particularly relies on the therapeutic relationship between HPs and patients. Therefore, allocating sufficient human and financial resources to mental health care aiming to further support the relationship between patients and HPs is of utmost importance.

RESUMO

PURPOSE: We present our experience of using the Anterior Combined Endopelvic (ACE) approach, which consists of a combination of a newly modified Stoppa approach with the lateral approach to the iliac crest. This approach is discussed in terms of fracture reduction and fixation, technical aspects, and the incidence of complications, and as an alternative to the ilioinguinal approach for the treatment of acetabular fractures. METHODS: A consecutive group of 34 adult patients with acetabular fractures treated surgically with the ACE approach was compared with a group of 42 adult patients treated with the ilioinguinal approach between 2010 and 2013. Both approaches were performed by a single surgeon to fix the acetabular fractures with main anterior displacement and the anterior and lateral parts of the pelvis. All the patients were analysed with typical X-ray projections for acetabular fractures and CT-scan. Charts and radiographs were reviewed for fracture pattern. Operative time, blood loss, quality of reduction, functional outcomes and perioperative complications were compared between the two groups of patients. RESULTS: The mean follow-up of patients was 26 months (range 6-49 months), with a median of 24.5 months. The types of acetabular fraction in the study were as follows: 32 anterior and posterior columns, 18 anterior columns, 10 anterior columns with posterior hemitransverse, 10 transverse associated with posterior walls, two transverse; two T-Type transverse and two anterior walls. Average blood loss was 1090 mL in the ACE group and 1200 mL in the ilioinguinal group. Anatomic or satisfactory reduction was achieved in 94% of the acetabular fractures. Two patients (one in each group) had mild symptoms of the lateral femoral cutaneous nerve and improved within 4-6 months; one patient in the ilioinguinal group developed ossification Brooks grade III. CONCLUSION: The ACE approach for the treatment of acetabular fractures is highly recommended when the fracture involves the quadrilateral surface and anterior column. This approach provides a direct good-to-excellent visualisation and access to the entire fracture, which makes reduction and fixation easier. The clinical outcomes were slightly better with ACE compared with the ilioinguinal approach. Complication rate was similar in the two groups. The ACE technique is a viable alternative to the ilioinguinal approach when exposure of the anterior acetabulum is required.

RESUMO

PURPOSE: Companions often accompany patients to cancer consultations. The number of questions asked by patients and companions is an indicator of their active participation. The present study aims to provide first descriptive evidence on the characteristics of unaccompanied and accompanied Italian breast cancer patients that attend the first consultation after surgery and to analyse companions contribution to the type and quantity of questions asked during the consultation. METHOD: Seventy consultations of female patients with breast cancer were audio taped. Questions were transcribed and coded by content. Companion's questions were also classified in terms of function. Socio-demographic and clinical data, patients' role preference and confidence in decision making measures were gathered for each patient. Post consultation satisfaction with decision and the perceived level of shared decision making were collected either for the patient and the companion. RESULTS: 69% of patients were accompanied, usually by one close family member, either husband or adult child. Non employed or retired patients and those with a preference for passive role in decision making were more likely to be accompanied. Unaccompanied patients and accompanied patients had comparable levels of anxiety, emotional distress and depression and were equally active in asking questions. These levels were far greater than those reported for other cancer patients in the literature. Companions did not increase significantly the number of questions per consultation. CONCLUSION: Accompanied and non accompanied patients differed more in socio-demographic than clinical characteristics. Companions sustained the patient and shared information without reducing the level of patient involvement.

RESUMO

This study focused on the expression of somatotropic axis genes in the skeletal muscle of dairy cattle. A slow-release recombinant bovine growth hormone (GH) (rbGH) formulation was administered to 5 cows, and saline solution (control) was administered to another 5 cows every 2 wk for a total of 10 wk, starting from the peak of lactation. Tissue and blood samples were collected on days 2 and 14 after each rbGH injection. As target genes insulin-like growth factor (IGF)-1, IGF-2, IGFBPs (1, 2, 3, 4, 5, 6), acute labile subunit (ALS), IGF-1 receptor (IGF-1R), GH receptor (GHR), and the known GHR 5'-UTR variants were selected as target genes, and their relative expression was measured using real-time polymerase chain reaction. In GH-treated cows, an increase in expression was observed for GHR 5'-UTR variant 1I on day 14 (P < 0.05), whereas a significant down-regulation of GHR (P < 0.05) was found after comparing values of treated cows between day 2 and day 14. However, only IGF binding proteins (BP)-5 was found to be appreciably up-regulated in GH-treated cows (P < 0.001), which may indicate the importance of this gene in the overall molecular response to GH administration. Our study indicated that GH treatment did not affect the expression of most somatotropic axis genes, despite the marked increase in GH and IGF-1 in blood (P < 0.001). Nor did it have a large impact on the proportion of GHR 5'-UTR variants in the skeletal muscle of lactating cows. Finally, although we observed a significant variation in the expression of some genes, it would appear that the differences between GH-treated cows and controls were not great enough to be considered as reliable indirect indicators of GH treatment in dairy cattle.

RESUMO

BACKGROUND: Communication skills are considered 'core skills' in the curriculum of psychiatry but studies evaluating the effectiveness of a time-limited training course in interviewing skills in psychiatry have remained rare. The aim was to assess the effectiveness of training in patient-centred interviewing on the interview performance of psychiatric residents. METHOD: Psychiatric residents (n=10) each interviewed 12 different anonymized standardized patients (SPs), eight before and another four after training. SPs simulated psychiatric out-patients who attended for a first visit to the psychiatric out-patient clinic. The consultations were videotaped, transcribed and coded with a classification scheme developed for psychiatric consultations from which an interview performance index was derived. An interrupted time-series design and a segmented regression analysis with multilevel analysis explored the performance trend within the series of consultations. RESULTS: The regression model evidenced a horizontal slope at pre- and post-training, with a significant level change. These findings excluded the presence of a practice effect and indicated a significant effect of training. Performance variability between and within residents over the series of consultations increased at post-training. CONCLUSIONS: The training improved patient-centred interviewing performance. More post-training exercise time and supervised practice are necessary to establish consistent performance patterns at a higher skill level.

RESUMO

E-cadherin (cadh), a member of a family of integral membrane glycoproteins that represent the major component of adherens junctions (AJs), mediates cell-cell adhesion through the calcium-dependent homophilic interaction of its extracellular domain. Metastatic human carcinomas frequently lose E-cadh expression, whereas epithelial ovarian cancer (EOCs) maintain properties characteristic of Müllerian epithelium during tumor progression, including E-cadh expression. Here, we examined the potential role of cell-cell contacts in EOCs through E-cadh homophilic interactions in PI3K/AKT activation whose altered signaling has been implicated in EOC pathogenesis. We show that E-cadh is predominantly expressed at cell-cell contacts and its functionality is necessary and sufficient for the activation of the PI3K/AKT pathway. E-cadh knockdown and phosphoinositide-3-kinase (PI3K) inhibition complement each other in impairing cell-cycle progression and proliferation of ovarian carcinoma cells. E-cadh is stably bound to the PI3K complex, and the de novo formation of E-cadh/beta-catenin complexes following calcium deprivation and subsequent calcium restoration recruits the PI3K p85 subunit to the site of the cell-cell contacts. The finding that E-cadh-mediated AJ formation contributes to PI3K/AKT activation in EOC cells by a mechanism that appears to be restricted to these cells provides the underpinning for therapeutic strategies that exploit PI3K inhibition to halt EOCs.

RESUMO

BACKGROUND AND AIMS: Flow mediated dilation (FMD) of peripheral conduit arteries is a well-established tool to evaluate endothelial function. The aims of this study are to apply the FMD model to cerebral circulation by using acetazolamide (ACZ)-induced intracranial vasodilation as a stimulus to increase common carotid artery (CCA) diameter in response to a local increase of blood flow velocity (BFV). METHODS AND RESULTS: In 15 healthy subjects, CCA end-diastolic diameter and BFV, middle cerebral artery (MCA) BFV and mean arterial blood pressure (MBP) were measured at basal conditions, after an intravenous bolus of 1g ACZ, and after placebo (saline) sublingual administration at the 15th and 20th minute. In a separate session, the same parameters were evaluated after placebo (saline) infusion instead of ACZ and after 10 microg/m(2) bs and 300 microg of glyceryl trinitrate (GTN), administered sublingually, at the 15th and 20th minute, respectively. After ACZ bolus, there was a 35% maximal MCA mean BFV increment (14th minute), together with a 22% increase of mean CCA end-diastolic BFV and a CCA diameter increment of 3.9% at the 3rd minute (p=0.024). There were no MBP significant variations up to the 15th minute (p=0.35). After GTN administration, there was a significant increment in CCA diameter (p<0.00001). CONCLUSIONS: ACZ causes a detectable CCA dilation in healthy individuals concomitantly with an increase in BFV. Upon demonstration that this phenomenon is endothelium dependent, this experimental model might become a valuable tool to assess endothelial function in the carotid artery.

RESUMO

BACKGROUND: Several studies indicate that subjective experience toward antipsychotic drugs (APs) in schizophrenic patients is a key factor in ensuring a smooth recovery from the illness. OBJECTIVE: The principal aim of this study was to establish the psychometric performance of the Subjective Well-being Under Neuroleptic (SWN) scale in its Italian version and to assess, through the SWN scale, the subjective experience of stabilized psychotic outpatients in maintenance with APs. METHODS: The original short version of SWN, consisting of 20 items, was back translated, and a focus group was also conducted to better improve the comprehension of the scale. RESULTS: The results showed a good performance of the Italian version of the SWN as documented by the internal consistency (Cronbach's alpha; 0.85). A satisfactory subjective experience was reported in the sample of schizophrenic outpatients interviewed (SWN mean total score: 84.95, SD: 17.5). CONCLUSIONS: The performance of the SWN scale in the present study was very similar to that reported by Naber et al. in the original validation study. Large multi-center studies are needed to better establish differences in the subjective experience of schizophrenic patients treated with first- and second-generation APs.

RESUMO

OBJECTIVE: To assess the effect of socioeconomic status (SES) on psychiatric service use in an Italian area with a well-developed community-based psychiatric service. METHOD: An index of SES was calculated from nine census variables and grouped into four categories, ranging from SES-I-affluent to SES-IV-deprived, for each of 328 census blocks (CB). Fifteen indicators of psychiatric service use were collected using the psychiatric case register. All patients resident in the catchment area, who had at least one psychiatric contact in 1996 (n=989), were included in the study. RESULTS: Indicators of in-patient, day-patient, out-patient and community service use showed an inverse association with SES. Only first-ever and long-term psychotic patients were equally distributed in the four SES groups. CONCLUSION: The inverse association between SES and most indicators of psychiatric service use suggests that the planning of community-based services and resource allocation should take into account the SES of residents.

RESUMO

The simultaneous temperature and inlet pressure programming (TPP) in gas chromatographic analysis decreases the retention time and the maximum value of temperature required for the elution of high boiling substances. Therefore, compounds sensitive to thermal degradation can be better analysed and column ageing is reduced. However, the empirical choice of proper analysis conditions requires many preliminary runs; this paper describes a procedure for the theoretical prediction of retention times in TPP using few preliminary runs carried out in isobaric and isothermal conditions. The used program permits the prediction of the retention times of the compounds analysed with any different TPP run carried out within the temperature and pressure ranges investigated with the preliminary runs. The influence of various analytical parameters on the accuracy of the prediction values was investigated. The proposed model also predicts the relative position in the chromatogram of closely eluting peaks and the possible coincidence of retention times or inversion of the elution order with changing temperature. It is also possible to foresee the analytical conditions, which offer a baseline separation of all of the peaks of the sample.

RESUMO

BACKGROUND: In primary care the General Health Questionnaire (GHQ) is used to provide an independent assessment of probable caseness of psychological disorder against which to test the ability of the general practitioner (GP) to recognize patients with current emotional problems. METHOD: The aim of the present study was to identify those clinical and psychosocial data on patients that increase the likelihood of GPs' attribution of emotional distress (GP model) and those that predict patients' emotional distress as defined by the GHQ-12 (GHQ model). The associations were explored using a classification tree technique (CHAID) and compared using bivariate logistic regression. Six GPs and 444 primary care patients took part. RESULTS: The accuracy indices of the hierarchical GP and GHQ models were 72% and 69% respectively. The availability of information on patients' psychopharmacological and psychiatric/psychological treatment in the last year was the most important predictor of attribution. Occupational, financial and housing problems and life events of loss were the most important predictors of the GHQ-12 case definition. The overall accuracy of the bivariate model was 73%. Compared with the GHQ-12, GPs gave significantly more importance to psychiatric treatment, psychopharmacological drug use and chronic illness. CONCLUSIONS: The findings suggest that to improve the detection of current emotional distress in primary care patients GPs should pay foremost and systematic attention to social problems and recent life events of loss. These problems are important clues for the possible presence of emotional distress, whereas critical patient data, in particular psychiatric history and psychopharmacological treatment, increase the probability of attribution errors.

RESUMO

The human folate receptor (FR) is overexpressed in ovarian carcinoma. FR transcripts are heterogeneous due to the use of two promoters, P1 and P4, and alternative splicing of exon 3. RNase protection assay and RT-PCR revealed higher levels of the transcripts that include exon 3 in lines and specimens from ovarian carcinoma. A P1-chloramphenicol acetyltransferase (CAT) construct containing exon 3 demonstrated efficient reporter expression only in ovarian carcinoma. 5' and 3' deleted variants of the P1-CAT construct were analyzed by RT-PCR of the exogenous transcripts and reporter activity. A 5' splice site and 35 bp downstream intronic region of exon 3 appeared to regulate enhanced FR expression in ovarian carcinoma.

RESUMO

The alpha-folate receptor (alpha FR) is overexpressed in 90% of nonmucinous ovarian carcinomas. In addition to the known role of alpha FR binding and mediating the internalization of folates, functional interaction of alpha FR with signaling molecules was recently shown. To identify a model to study the role of alpha FR in ovarian carcinoma, we characterized the alpha FR gene in the ovarian carcinoma cell line CABA I in comparison to a reference line, IGROV1. In CABA I cells, Northern blot analysis revealed an alpha FR transcript of the expected length and FACS analysis indicated receptor expression on the cell membrane; however, RNase protection assay revealed no specific signals. Southern blot and genomic PCR analysis suggested the presence of a rearrangement(s) involving the 5' region of the gene in CABA I cells as compared to IGROV1 cells. Cloning and sequencing of CABA I alpha FR cDNA revealed several point mutations. The partitioning of alpha FR in membrane microdomains from CABA I cells and its association with regulatory molecules was comparable to that of IGROV1 cells. By contrast, the alpha FR expressed on the CABA I cell membrane bound folic acid with lower affinity, and ectopic expression of the corresponding cDNA in CHO cells confirmed impaired folic acid binding. Thus, CABA I cells may provide a tool to delineate functional domains of the alpha FR.

RESUMO

OBJECTIVE: The present study aims to assess needs for care rated by patients and staff and their agreement on needs assessment in a community-based mental health service by using the Camberwell Assessment of Need (CAN). METHOD: The Italian version of the CAN was used in a sample of 247 patient-staff pairs. RESULTS: Patients and staff showed poor agreement on both the presence of a need and on whether need had been met or not. Higher disability predicted a higher number of patient-rated needs, while higher disability, higher number of service contacts and patient unemployment predicted a higher number of staff-rated needs. Lower global functioning predicted higher disagreement in patients and staff ratings of needs. CONCLUSION: Patients and staff show different perceptions of needs for care and therefore multiple perspectives should be taken into account for planning and providing effective needs-led mental health care.

RESUMO

BACKGROUND: The next generation of studies on antidepressant drug prescriptions in general practice needs to assess both the patterns of prescription and its appropriateness. This study aimed to assess the performance of the Personal Health Questionnaire (PHQ), a new questionnaire for detecting individuals with ICD- 10 depressive disorders, to be used in association with companion instruments for assessing the 'quality' of antidepressant prescriptions in primary care settings. METHODS: The PHQ was completed by 1,413 primary care attenders (100 were re-tested after 7-14 days) and 139 were selected and interviewed using the SCAN-2 and the 17-item HDRS. All data were analysed using appropriately weighted procedures to control for two-phase sampling design and non-response bias. Individual weights were estimated by logistic regression analysis and trimming strategy. RESULTS: PHQ internal consistency and test-retest on both Likert score and number of symptoms were high. The PHQ discriminated well between individuals with and without depressive disorders. A Likert score > or = 9 provided a good trade-off between sensitivity (0.78) and specificity (0.83). The screening accuracy of the PHQ in detecting subjects likely to benefit from antidepressant drug treatment (SCAN cases with a HDRS total score of 13 or higher) was satisfactory (ROC area 0.87: sensitivity 0.84; specificity 0.78). CONCLUSIONS: The PHQ can be strongly suggested as an accurate and economic screener to identify primary care attenders at high risk of being clinically depressed. However, in order to identify patients requiring antidepressant drug treatment, a second-phase assessment of PHQ high scorers (total score of > or = 10), using the HDRS, is needed.

RESUMO

The alpha isoform of the folate receptor (FR) is a 38-KDa glycosylphosphatidylinositol (GPI) protein which mediates the internalization of folates. The FR amino acid sequence has features typical of GPI-linked proteins, including the presence of a hydrophobic carboxyl-terminus, a hinge region, and a stretch of small and uncharged amino acids. Substitution of predicted cleavage/attachment Ser234 with arginine or threonine, or replacement of Gly235 with proline by site-directed mutagenesis had no effect on GPI processing. In fact, CHO cells transfected with each of the three cDNA variants or with FR wild-type showed comparable amounts of phosphatidylinositol-specific phospholipase C-resistant FR in double-determinant radioimmunoassay. Western blot analysis of total cell lysates from all transfectants consistently revealed the 38-KDa FR band. Deletion of residues 233-237 in the amino-terminal portion of the FR cDNA constructs derived by a polymerase chain reaction strategy abrogated GPI processing, with only a small proportion of the FR remaining in the cytoplasm in four of the five clones tested. This finding suggests that FR residues 233-237 are essential in properly juxtaposing the FR hydrophobic domain. Together, these data support the hypothesis that the postulated Ser234 is not the only potential cleavage/attachment site of the alpha isoform of FR.

RESUMO

Oral malignant neoplasms are very common in old dogs. The prognosis of oral malignant melanoma (MM) for long-term survival is poor, because of early metastasis and delayed diagnosis. Oral MM in immature dogs is rare. A case of oral MM in an immature dog is described. The diagnostic workup includes radiographs of the tumor and thorax, a cytologic examination of the regional lymph nodes and a biopsy of the tumor. The therapy with the best chance of success is the radical surgical excision of the tumor.
