Task-Based Automatic Evaluation of People with Intellectual Disabilities Performed on a Robotic Table Soccer

This paper is concerned with the automatic evaluation of selected tasks performed by people with intellectual Disabilities. According to the International Classification of Functioning, Disability and Health (ICF) system, subjects must be divided into two groups: group with no difficulty (N) and group with difficulty (D) being this classification based on performances obtained in a conventional table (CT) soccer. Three tasks, with different levels of difficulty, were proposed for performance evaluation. Experimental results were obtained on the basis of the task execution in both a CT and a robotics table (RT) soccer. All participants were able to perform tasks with the joystick on the RT soccer and the automatic evaluation system identified differences in reaction times with and without red color flag in the participants, on RT soccer. One of the tasks was completely performed by all the participants by using the RT soccer.

Organ Donation and Transplantation as Health Programs in Italy

Organ and tissue donation and transplantation have a role in public health programs as organizational projects designed by public health departments to increase the quality and number of donations and transplantations. These programs serve as communication projects to inform public opinion on cerebral death, organ and tissue shortages, procurement and allocation rules, and the quality of life of transplanted patients. The health department of Emilia-Romagna created a regional law and a multimedia communication program for these purposes, resulting in a 95% increase of cadaver donor in 4 years. In 1995, regional activity reached the European mean level and afterwards surpassed it. In 1997, the bone bank was activated, followed in 1998 by the heart valve and vascular segment bank. The regional health department now considers transplant activities a primary goal; human and professional relations between intensive care units and the transplant reference center are considered crucial; cooperation among health departments, medical teams involved in organ procurement and transplant activities has been fostered, and the local coordination network has been active and efficient. The public information campaign has proven important in providing information both to professionals and citizens.

Reliability of Ultrasound Screening of Liver and Kidney Donors: A Retrospective Study

The reliability of abdominal ultrasound in screening liver and kidney donors was assessed by correlating ultrasound findings with the suitability of organs for transplantation as determined by direct examination of the organs. We evaluated 100 multiorgan donors (100 livers, 200 kidneys) during a 15-month period. Abdominal ultrasound showed the following results for liver and kidney, respectively: specificity, 95.6% and 98.9%; sensitivity, 62.5% and 66.6%; and accuracy, 93% and 97%. These results show that abdominal ultrasound is a valuable tool for determining suitability of organs for transplantation when the ultrasound findings are normal. When ultrasound findings are abnormal, further studies are necessary to determine the suitability of the organs for transplantation.

Posterior reversible encephalopathy syndrome in lung transplantation: 5 case reports

Posterior reversible encephalopathy syndrome (PRES) is a cliniconeuroradiologic entity characterized by typical neurologic symptoms with characteristic cerebral image alterations. It has been reported in solid organ transplantations, especially related to the use of calcineurin inhibitors. The incidence of PRES in lung transplantation is unknown and probably under-reported in the literature. Here we describe 5 cases of PRES after bilateral lung transplantation. One of the reported cases was the first in the literature in which the neurologic onset precluded the introduction of calcineurin inhibitor. Therefore, although calcineurin inhibitors are known to play an important role in the development of PRES in the setting of lung transplantation, other causes seems to be involved in the physiopathology of this syndrome.

Epipericardial fat necrosis: an underdiagnosed condition

OBJECTIVE

Epipericardial fat necrosis (EFN) is an uncommon benign and self-limited condition that leads patients to the emergency department (ED) owing to the onset of acute pleuritic chest pain. The aim of this study was to describe the cases of this disease in our institution and to illustrate the associated clinical and radiological findings.

METHODS

We reviewed 3604 chest scans referred by the ED from November 2011 to July 2013. Patients diagnosed with epipericardial necrosis had their medical records and original tomography reports analysed.

RESULTS

Chest pain was the primary complaint in 426 patients; 11 of them had definitive EFN findings characterized by a round soft-tissue attenuation lesion with a varying degree of strands. All patients presented with pleuritic chest pain on the same side as the lesion. Pericardial thickening, pleural effusion and mild atelectasis were the associated tomography findings. Cardiac enzyme and D-dimer tests performed during the episode were normal in all cases. 27% of the cases only were correctly diagnosed with EFN at the time of presentation.

CONCLUSION

EFN is a benign inflammatory condition frequently overlooked in the ED by physicians and radiologists but is an important factor in the differential diagnosis of patients with acute chest pain.

ADVANCES IN KNOWLEDGE

The article adds clinically and radiologically useful information about the condition and displays the importance of making the correct diagnosis to avoid unnecessary examinations.

Chronic paracoccidioidomycosis of the intestine as single organ involvement points to an alternative pathogenesis of the mycosis

Current knowledge on the natural history of paracoccidioidomycosis states that the chronic form of the disease results from reactivation of quiescent foci established years or decades before during the primary lung infection. Once reactivated, the fungi can disseminate to virtually any organ or system. We present herein two chronic paracoccidioidomycosis patients with a single organ involvement that points to an alternative pathogenesis of the mycosis. These patients suggest that the chronic form may also arise from reactivation of foci not confined to the lungs, due to the early dissemination of yeast cells during the primary infection.

European quality system for tissue banking

AIM

The aims of this project were to analyze the factors that influence quality and safety of tissues for transplantation and to develop the method to ensure standards of quality and safety in relation to tissue banking as demanded by European Directive 2004/23/EC and its technical annexes. It is organized in 4 Working Groups, the objectives of each one being focused in a specific area.

STANDARDS

The Guide of Recommendations for Tissue Banking is structured into 4 parts: (1) quality systems that apply to tissue banking and general quality system requirements, (2) regulatory framework in Europe, (3) standards available, and (4) recommendations of the fundamental quality and safety keypoints.

REGISTRY

This Working Group handled design of a multinational musculoskeletal tissue registry prototype.

TRAINING

This Working Group handled design and validation of a specialized training model structured into online and face-to-face courses. The model was improved with suggestions from students, and 100% certification was obtained.

AUDIT

The Guide for Auditing Tissue Establishments provides guidance for auditors, a self-assessment questionnaire, and an audit report form. The effectiveness and sustainability of the outputs were assessed. Both guides are useful for experienced tissue establishments and auditors and also for professionals that are starting in the field. The registry prototype proves it is possible to exchange tissues between establishments throughout Europe. The training model has been effective in educating staff and means having professionals with excellent expertise. Member states could adapt/adopt it. The guides should be updated periodically and perhaps a European organization should take responsibility for this and even create a body of auditors.

Human bronchial epithelial cells malignantly transformed by hexavalent chromium exhibit an aneuploid phenotype but no microsatellite instability

Hexavalent chromium [Cr(VI)] is a well-recognized human lung carcinogen. In order to gain further insight into Cr(VI)-induced carcinogenesis, we have established an adequate in vitro cellular model for the study of this process. To this end, BEAS-2B cells were used. Chronic exposure of cells to 1 microM Cr(VI) induced changes in the cells' ploidy and a decrease in cloning efficiency, although cultures continued to progress to confluence. After prolonged exposure (12 passages), the culture became heterogeneous, exhibiting areas where apparently normal epithelial cells and morphologically altered cells coexisted. Subsequent culture at a very low density strongly accentuated the Cr(VI)-induced changes in morphology and pattern of growth. Three individual colonies were then ring-cloned and expanded into three subclonal aneuploid cell lines. These subclonal cell lines showed changes in growth pattern and morphology, as well as a karyotype drift concomitant with the overexpression of genes commonly involved in malignant transformation (c-MYC, EGFR, HIF-1alpha and LDH-A). Moreover, when one of these cell lines (RenG2) was injected into nude mice, it showed the ability to induce tumors. This cell line revealed no microsatellite instability (MSI), which points to the expression of a functional MLH1 protein and an active mismatch repair (MMR) system. Therefore, the progression to malignancy of the BEAS-2B cells involved Cr(VI)-induced transformants that retained the ability to repair DNA damage, suggesting that genotoxicity underlies the ongoing carcinogenic process.

Quality Evaluation of Solid Organ Transplant in Italy for the Period 2000 to 2002 Data from the National Transplant Center

BACKGROUND

As part of the increased need for transparency and disclosure of information in health care, the Italian Minister of Health has commissioned the Superior Institute of Health to study health outcomes for several procedures, among which is solid organ transplants. We herein report the results of a quality evaluation of solid organ transplants and on the relationship between hospital volume of activity and outcomes, using the data routinely collected by the National Transplant Center during the period 2000 to 2002.

METHODS

We collected and analyzed all the information on solid organ transplants between 2000 and 2002, along with clinical information before and after transplant. Multivariate survival analysis was performed to adjust the follow-up data for the complexity of the cases. Correlation graphs are presented that assess the association between the number of transplants and the adjusted 1-year survival of both the organ and the patient.

RESULTS

One-year survival was 92.4% for kidney, 77.8% for liver, and 83.9% for heart. Patient survival was 97.0%, 84.1%, and 83.9%, respectively. A negative correlation was observed between the number of transplants performed by each center and 1-year survival of the organ.

CONCLUSIONS

Our study indicated that survival after organ transplants in Italy is good and that hospital quality, indirectly measured through survival, overlaps that observed in other Western countries.

Molecular monitoring of organ recipients from cancer-affected donors by detection of circulating tumor cells

We have initiated regular molecular monitoring based on nested RT-PCR detection of circulating tumor cells for monitoring recipients of organs from cancer-affected donors in Italy (in the context of a "Donation Safety and Donated Organ Quality" project organized by the Centro Nazionale Trapianti). Five patients are being monitored. For two patients who each received a kidney from a single donor with prostate adenocarcinoma, RT-PCR was performed using PSA mRNA. For three recipients of organs (two livers and one kidney) from donors with renal cell carcinoma, RT-PCR was performed using cytokeratine 18 and 19 mRNA. Blood samples from five healthy subjects were used as negative controls. After a median monitoring time of 26 months (range 8 to 32), none of the regular 3-month assays has tested positive. This pilot study suggests that detection of circulating tumor cells by nested RT-PCR may provide a feasible molecular monitoring, which might assist decision making regarding other forms of clinical surveillance.

Obsessive-compulsive symptoms in adults with history of rheumatic fever, Sydenham's chorea and type I diabetes mellitus: preliminary results

OBJECTIVE

Rheumatic fever (RF) associated with Sydenham's chorea (a neurological variant of RF), but not RF without chorea, has been acutely related to obsessive-compulsive symptomatology/disorder (OCS/OCD). This study investigated the presence of OCS in adults who had RF with or without chorea in childhood.

METHOD

The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to evaluate OCS in 38 adults with history of RF (13 with chorea; 25 without chorea) or diabetes (controls; n = 19).

RESULTS

The OCS was similar in both groups, although the intensity of symptoms was not clinically relevant. Moreover, subjects with RF with or without chorea did not score differently in the Y-BOCS.

CONCLUSION

The similar occurrence of OCS in patients with history of RF and diabetes suggests that the development of this symptomatology, triggered by group A beta-haemolytic streptococcus infections, is restricted to the RF acute phase, occurred during infancy, and did not seem to predispose the appearance of OCS in adulthood.

Hospital attitude survey on organ donation in the Emilia-Romagna region, Italy

The role of hospital staff in the organ procurement process is crucial. Nevertheless, there is little literature about their attitudes toward donation. The Donor Action Hospital Attitude Survey (HAS) comprises a series of questions to assess hospital staff's attitudes, beliefs, and knowledge on organ donation and transplantation. Further analysis of the data will help identify any weak areas in the staff viewpoint and information, highlight potential needs for more education on specific issues, and establish a baseline to monitor future improvements. We used the Donor Action HAS in the Emilia-Romagna region, Italy. The aim of this paper is to assess and better understand the personnel's viewpoint in the 12 main hospitals of the region. The survey was carried out among hospital staff involved in organ donation. 1576 responses were collected (52 % of distributed questionnaires), of which 1024 came from nurses, 475 from physicians, and 77 from other backgrounds. Questions were subdivided into categories, and for every point an overall mark (maximum 3/3) was calculated.

RESULTS

1. Involvement in donation process during the past year: 1.24 /3, 2. Attitudes to organ donation (OD): 2.51 /3, 3. Skills / Self-confidence in donation practices: 1.36 /3, 4. Satisfaction with local transplant coordinator (TC) services: 2.31 /3. The attitude towards organ donation was positive, 1386 respondents support organ donation. A high percentage (93.6 % of respondents) is of the opinion that transplantation helps save other people's lives. Most uncertainty arises on the question whether donation helps families with grief. It is remarkable that only 53 % of those prepared to donate organs have informed the family of their wish. Many respondents do not feel comfortable performing key tasks close to donation. Major difficulties were observed in explaining to a family the concept of brain death (0.98 /3). Knowledge on the concept of brain-death was one of the most requested subjects for improvement. Emilia-Romagna is the region with one of the highest donation rates in Italy (29.9 pmp in 2000). Nevertheless, more profound knowledge of the local situation could help further improve donation.

Impact of dietary lysine intake during lactation on follicular development and oocyte maturation after weaning in primiparous sows

Primiparous sows (n = 36) were used to evaluate the effects of dietary lysine intake in lactation on follicular development and oocyte maturation after weaning. Sows were assigned randomly to one of three diets containing .4% (low lysine, LL), 1.0% (medium lysine, ML), or 1.6% (high lysine, HL) total lysine. All diets contained 2.1 Mcal NE/kg and exceeded NRC (1988) requirements for all other nutrients. Actual lysine intakes over an 18-d lactation were 16, 36, and 56 g/d for sows consuming LL, ML, and HL, respectively. Ovarian data were analyzed for sows determined to have been slaughtered during the first proestrus period after weaning, using previously established criteria. Compared with sows fed ML and HL, sows fed LL tended to have lower uterine weight, follicular fluid volume, and follicular fluid (FF) estradiol (E2) content (P < .15), but similar ovarian weight and follicular fluid IGF-I concentration. Within the largest 15 preovulatory follicles, sows fed LL had a lower percentage of large (> or = 7.0 mm) follicles (33 vs 50 and 58%; P < .01) and a higher percentage of medium (5.5 to 7.0 mm) follicles (62 vs 44 and 39%; P < .01) but a similar percentage of small (< or = 5.5 mm) follicles (4.4 vs 5.9 and 3.7%; P > .15), respectively, compared with sows fed ML or HL. Standardized pools of oocytes aspirated from follicles of prepubertal gilts were incubated for 44 h with pooled FF recovered from the largest 15 follicles of each experimental sow. Fewer oocyte nuclei matured to metaphase II of meiosis when cultured with FF recovered from sows fed LL, than from sows fed ML or HL (47.1 vs 59.8 and 63.8%, respectively; P < .01). Our results suggest that low lysine (protein) intake in primiparous lactating sows impaired follicular development and reduced the ability of follicles to support oocyte maturation. However, high compared with medium lysine (protein) intake had no further positive effects on ovarian function.

Altered thymic endocrine activity along with impairments of peripheral zinc metabolism and T-lymphocyte populations are associated with myasthenia gravis: a follow-up study

Thymic endocrine activity was assessed by a bioassay to determine the basal activity of thymulin (TH), a zinc dependent hormone, and its in vitro reactivation in two different age groups of patients with myasthenia gravis (MG). Before thymectomy, basal TH plasma levels were increased in patients over the age of 50 years. Plasma zinc levels were increased in all patients, this increment being very high in old patients. One year after thymectomy both TH and zinc plasma levels decreased. While zinc plasma levels were within the normal ranges for their respective ages, TH levels were lower in young and higher in old patients than in age comparable controls. Young patients with MG showed increased CD3,DR positive peripheral T-cells as well as lymphocytes with the CD16,CD56 phenotype. An increment of CD3 positive cells along with CD4 and CD16,CD56 positive cells were found in older patients. Thymectomy partially affected blood lymphocyte representation only in young patients, since CD3,DR T-cells decreased one year after surgery. No significant variations in T-cell representation were found in old patients after thymectomy. Immunosuppression in thymectomized patients did not significantly affected TH and zinc plasma levels. Very high levels of TH and the presence of additional alterations in T-lymphocyte subsets in old patients suggested that differential age related pathogenetic immunological mechanisms might be associated with the disease.

The presence of posttransplant HLA-specific IgG antibodies detected by enzyme-linked immunosorbent assay correlates with specific rejection pathologies

Posttransplant monitoring of anti-HLA antibodies with routine techniques gives unsatisfactory results due to a variety of technical limitations. We investigated how a new alternative technique correlates with posttransplant clinical events. A total of 313 nonselected serum samples from 136 patients were screened by an ELISA utilizing captured soluble HLA class I antigens. We observed the absence of anti-HLA antibody production in acute rejection cases responding to standard antirejection therapy. On the other hand, we showed a clear presence of these antibodies in acute rejection episodes not responding to standard therapy (P<0.0001) and in chronic rejection (P<0.001). We conclude that routine posttransplant monitoring by ELISA offers early risk assessment that is crucial for proper immunosuppression and for antirejection therapy choice.
