Occupational Therapy Task Observation Scale (OTTOS) and Comprehensive Occupational Therapy Evaluation Scale (CO-TES): Italian translation, adaptation, and validation

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.

A concept for integrated care pathways for atopic dermatitis-A GA2 LEN ADCARE initiative

INTRODUCTION

The integrated care pathways for atopic dermatitis (AD-ICPs) aim to bridge the gap between existing AD treatment evidence-based guidelines and expert opinion based on daily practice by offering a structured multidisciplinary plan for patient management of AD. ICPs have the potential to enhance guideline recommendations by combining interventions and aspects from different guidelines, integrating quality assurance, and describing co-ordination of care. Most importantly, patients can enter the ICPs at any level depending on AD severity, resources available in their country, and economic factors such as differences in insurance reimbursement systems.

METHODS

The GA2 LEN ADCARE network and partners as well as all stakeholders, abbreviated as the AD-ICPs working group, were involved in the discussion and preparation of the AD ICPs during a series of subgroup workshops and meetings in years 2020 and 2021, after which the document was circulated within all GAL2 EN ADCARE centres.

RESULTS

The AD-ICPs outline the diagnostic procedures, possible co-morbidities, different available treatment options including differential approaches for the pediatric population, and the role of the pharmacists and other stakeholders, as well as remaining unmet needs in the management of AD.

CONCLUSION

The AD-ICPs provide a multidisciplinary plan for improved diagnosis, treatment, and patient feedback in AD management, as well as addressing critical unmet needs, including improved access to care, training specialists, implementation of educational programs, assessment on the impact of climate change, and fostering a personalised treatment approach. By focusing on these key areas, the initiative aims to pave the way for a brighter future in the management of AD.

[Health related to quality life of patients with hereditary angioedema in Argentina. A multicenter study]

OBJECTIVE

To describe health relaed quality of life in a cohort of stable adult outpatients with hereditary an-gioedema (HAE) with validated tools.

METHODS

An observational, cross-sectional, and descriptive study was performed, carried out in patients with hereditary angioedema, coming from the City of Buenos Aires and its provinces: Corrientes, Chubut, Entre Ríos and Santa Fe. The HAE-QoL and SF-12v2 health questionnaires were applied to assess the related quality of life. with health.

RESULTS

100 patients were included; median age: 41.5 years (range: 18-77); 65% were female, and 79% had type 1 HAE. Asymptomatic, mild, moderate and severe cases accounted for 6, 29, 38, and 27% of participants, respectively. Seventeen percent of patients were receiving long-term prophylaxis. Icatibant was the most fre-quent treatment for acute episodes. All health domains SF-12v2 scores were lower than expected in general population, excepting "vitality" and "physical functioning". Total and all specific domains HAE-QoL scores were reduced. Differences between women and men and in every age-defined group were demonstrated for sev-eral specific domains.

CONCLUSIONS

Health relaed to quality life was notably reduced in Argentinean patients with HAE, when imple-menting the HAE.QoL, and SF-12v2 questionnaries. The need for multidisciplinary strategies approaching this complex disease is highlighted.

Italian translation, cultural adaptation, and validation of the Intermittent Catheterization Acceptance Test (I-CAT)

Aims

The purpose of the present study was to translate and culturally adapt the Intermittent Catheterization Acceptance Test (I-CAT) for Italian individuals with spinal cord injury and spina bifida and to measure its psychometric properties.

Methods

Consent from the authors of I-CAT was received, and then, following international guidelines, it was culturally adapted to Italian. The included participants adults who practice self-catheteri-zation. In order to evaluate criterion validity, the Qualiveen-30, Spinal Cord Independence Measure (SCIM-self reported), and the Moorong self-efficacy scale (MSES) were administered together. Test-retest reliability was assessed administering the I-CAT a second time within a week. Following the COSMIN checklist, psychometric properties were evaluated.

Results

All translated items resulted identical or similar to the original versions. Internal consistency, evaluated on 34 individuals, showed values of Cronbach's alpha of 0.889, test-retest reliability was evaluated through the intraclass correlation coefficient with values of 0.96. Statistically significant correlation between the I-ICAT and Qualiveen were found through Pearson's correlation coefficient and Spearman's Correlation Coefficient for criterion validity.

Conclusions

The Italian validation of I-CAT allows Italian professionals to investigate psychological barriers linked with self-catheterization in people with urinary tract dysfunction before learning about aseptic Intermittent Self Catheterization (IC) and improving patients' acceptance of it. This tool can also be used as follow-up after the training of intermittent self-catheterization techniques. Finally, it is an important tool for medical research.

Therapeutic educational workshops for caregivers of patients with severe acquired brain injury

Abstract

Severe acquired brain injury (sABI) leads to a wide range of functional limitations in cognitive, moto and behavioural abilities. These changes impact the patient's family in terms of the feeling of emotional and physical health, social life and financial condition. Caregivers are often intensely involved in the patient's management exposing them to negative effects of caregiving including stress, mood disorders and decreased quality of life. Implementing forms of active involvement of caregivers in the rehabilitative program could be useful. Thus, in the present study, therapeutic educational workshops (TEWs) for caregivers during the post-acute intensive hospitalization were organized during the post-acute intensive hospitalization of patients with sABI. The caregivers were asked to participate in the workshops to actively involve them in the patient's care and neurorehabilitation program. Each workshop session provided indications regarding the management of the patient with aphasia, neglect, behavioural and swallowing disorders. A questionnaire of 22 items has been designed in order to represent possible indicators of usefulness and effectiveness of the TEWs. The primary aim of this study was to develop a reliable and valid questionnaire able to assess the caregivers' satisfaction with the modalities of carrying out the TEW as a novel activity during the post-acute hospitalization of patients with sABI. The second aim was to assess the caregivers' satisfaction with the utility of the TEW as a tool to enhance their skills in the management of patients' disabilities. 100 caregivers of patients with sABI who attended at least one TEW session and completed the questionnaire were included in the analysis. In conclusion the administered questionnaire has proven to be a valid and reliable tool to evaluate sABI caregivers' satisfaction with TEW. Moreover, caregivers were satisfied with the organization of the TEW and with their usefulness in the management of the patients with sABI.

Correlation between Quality of Life and severity of Parkinson's Disease by assessing an optimal cut-off point on the Parkinson's Disease questionnaire (PDQ-39) as related to the Hoehn & Yahr (H&Y) scale

PURPOSE

Strong evidence shows that symptoms in individuals with Parkinson's Disease (PD) restrict both their independence and social participation, leading to a low Quality of Life (QoL). Conversely, a reduced QoL has a negative impact on symptoms. The aim is to evaluate the correlation between QoL and severity of PD by assessing the presence of an optimal cut-off point on the Parkinson's disease questionnaire (PDQ-39) as related to the Hoehn &Yahr (H&Y) scale in a cohort of Italian adults with PD.

METHODS

A multicenter, cross-sectional study was performed. This study was conducted on a cohort of consecutive individuals. All participants were evaluated with the PDQ-39, and the severity of PD was recorded according to the H&Y scale by a neurologist. Receiver op-erating characteristic (ROC) curves and coordinates, visually inspected, were used to find cut-off points with optimal sensitivity and specificity. These were in turn used to determine the optimal PDQ-39 cut-off score for identifying disease severity according to H&Y stages.

RESULTS

513 individuals were included in the study. The ROC curve analysis showed that QoL worsened with an increase in disease severity and age. Moreover, QoL was worse in females.

CONCLUSIONS

The results of this study allowed for the correlation of QoL and disease severity in a cohort of individuals with PD. With this cut-off point, it is now possible to make a determination of QoL of an individual with PD at a certain stage of the disease, in a specific age range, and of a particular gender.

Study of the relationship between regional cerebral saturation and pCO2 changes during mechanical ventilation to evaluate modifications in cerebral perfusion in a newborn piglet model

Near-infrared spectroscopy (NIRS) could be a useful continuous, non-invasive technique for monitoring the effect of partial pressure of carbon dioxide (PaCO₂) fluctuations in the cerebral circulation during ventilation. The aim of this study was to examine the efficacy of NIRS to detect acute changes in cerebral blood flow following PaCO₂ fluctuations after confirming the autoregulation physiology in piglets. Fourteen piglets (<72 h of life) were studied. Mean arterial blood pressure, oxygen saturation, pH, glycemia, hemoglobin, electrolytes, and temperature were monitored. Eight animals were used to evaluate brain autoregulation, assessing superior cava vein Doppler as a proxy of cerebral blood flow changing mean arterial blood pressure. Another 6 animals were used to assess hypercapnia generated by decreasing ventilatory settings and complementary CO₂ through the ventilator circuit and hypocapnia due to increasing ventilatory settings. Cerebral blood flow was determined by jugular vein blood flow by Doppler and continuously monitored with NIRS. A decrease in PaCO₂ was observed after hyperventilation (47.6±2.4 to 29.0±4.9 mmHg). An increase in PaCO₂ was observed after hypoventilation (48.5±5.5 to 90.4±25.1 mmHg). A decrease in cerebral blood flow after hyperventilation (21.8±10.4 to 15.1±11.0 mL/min) and an increase after hypoventilation (23.4±8.4 to 38.3±10.5 mL/min) were detected by Doppler ultrasound. A significant correlation was found between cerebral oxygenation and Doppler-derived parameters of blood flow and PaCO₂. Although cerebral NIRS monitoring is mainly used to detect changes in regional brain oxygenation, modifications in cerebral blood flow following experimental PaCO₂ changes were detected in newborn piglets when no other important variables were modified.

Development and validation of a test for the assessment of knowledge learned by healthcare students during an online course on COVID-19: cross-sectional study

Abstract

Many Italian universities during the COVID-19 pandemic had numerous students attending hospital wards. The training of health care students was necessary to prepare for good practices in implementing knowledge about COVID-19 and minimizing contagion among students who carried out the internship. In February 2020, a course aiming to guide health personnel so that they can appropriately address the health emergency posed by the new coronavirus was created, making use of the scientific evidence currently available as well as official sources of information and updates. The aim of this study was the development and validation of a useful tool to evaluate the progress in knowledge regarding COVID-19 of students in degree courses for the health care professions. The reliability of the test was assessed using Cronbach's alpha (α) coefficient, while the responsiveness of the test between T0 and T1 was measured with a student t test. The standard error of measurement was used to calculate the minimal detectable change of the tool. The test is made up of 31 items with four multiple-choice answers, one of which is correct. Fifteen bachelor's degree courses at the Sapienza University of Rome were enrolled, for a total population of 1,017 students from different course years. The test showed good internal consistency, with Cronbach's α values of 0.82. The item-total analysis also showed good results, with homogeneous α values from 0.80 to 0.82 for each item. The student t test showed a difference of 3.59 between T0 and T1 (p < 0.001). The minimal detectable change was 0.47. The test is a useful tool for assessing progress in skills regarding COVID-19 for students from bachelor's degree courses in the health professions. It allows the improvement and acquisition of skills as well as a qualitative analysis of the organization of internship degree courses.

Brief comments on three existing approaches for managing neonates at risk of early-onset sepsis

Background

Growing concerns regarding the adverse effects of antibiotics during the first days of life and the marked reduction in the incidence of early-onset sepsis (EOS) are changing the clinical practice for managing neonates at risk of EOS. Strategies avoiding unnecessary antibiotics while promoting mother-infant bonding and breastfeeding deserve to be considered.

Main body

We compare strategies for managing newborns at risk of EOS recommended by the American Academy of Pediatrics, which are among the most followed recommendations worldwide. Currently three different approaches are suggested in asymptomatic full-term or late preterm neonates: i) the conventional management, based on standard perinatal risk factors for EOS alone, ii) the neonatal sepsis calculator, a multivariate risk assessment based on individualized, quantitative risk estimates (relying on maternal risk factors for EOS) combined with physical examination findings at birth and in the following hours and iii) an approach entirely based on newborn clinical condition (serial clinical observation) during the first 48 h of life.

We discuss advantages and limitations of these approaches, by analyzing studies supporting each strategy. Approximately 40% of infants who develop EOS cannot be identified on the basis of maternal RFs or laboratory tests, therefore close monitoring of the asymptomatic but at-risk infant remains crucial. A key question is to know what proportion of babies with mild, unspecific symptoms at birth can be managed safely without giving antibiotics.

Conclusions

Both neonatal sepsis calculator and serial clinical observation may miss cases of EOS, and clinical vigilance for all neonates is essential There is a need to assess which symptoms at birth are more predictive of EOS, and therefore require immediate interventions, or symptoms that can be carefully reevaluated without necessarily treat immediately the neonate with antibiotics. Studies comparing strategies for managing neonates are recommended.

Italian version of the cornell musculoskeletal discomfort questionnaire (CMDQ-I): Translation, cultural adaptation and validation

BACKGROUND

Almost 25%of workers in the European Union suffer from back pain, and 23%complain of muscle pain. Sixty-two percent of workers carry out repetitive operations with their hands or arms, 46%work in painful or tired positions and 35%carry or handle loads.

OBJECTIVE

This study aimed to translate, culturally adapt and validate the Italian version of the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ-I).

METHODS

Translation and cultural adaptation procedures followed international guidelines. Participants were recruited from among the personnel components of the Italian Air Force, who were between 18 and 65 years old. Cronbach's alpha and the intraclass correlation coefficient (ICC) were calculated to assess internal consistency and stability, respectively. The CDMQ-I was administered together with the Visual Analogic Scale (VAS), and the validity was evaluated using Pearson's correlation coefficient.

RESULTS

All CDMQ-I items were either identical or similar in meaning to the original version's items. The scale was administered twice with a retest after seven to 10 days to 66 participants. Cronbach's alpha was higher than 0.761, and the ICC ranged between 0.737 and 0.952. Pearson's correlation coefficient showed positive and significant correlations (p > 0.01).

CONCLUSIONS

The study produced an Italian version of the CMDQ with good reliability and validity. This scale is a useful tool to investigate the frequency and intensity of musculoskeletal disorders in various categories of workers.

A systematic review of the psychometric properties of the Jebsen-Taylor Hand Function Test (JTHFT)

This systematic review of the literature aimed to identify studies examining the psychometric properties of the Jebsen-Taylor Hand Function Test (JTHFT) in various international populations on. The search was conducted in MEDLINE, SCOPUS, CINAHL and Web Of Science, with no restrictions on publication period, the country in which the study was conducted, or the age of the patients. Eligible studies were selected on the basis of inclusion criteria and data were extracted. Study quality and the risk of bias were assessed using the COnsensus-based Standards to select the health Measurement Instruments (COSMIN) checklist. 805 articles were identified; after removing duplicates, there were 361 single studies. 338 articles did not concern the psychometric properties of JTHFT. The remaining 23 studies were selected for full text review, and all were included. They comprised 8 languages and 9 pathologies. These findings suggest the JTHFT is a useful test of manual dexterity in activities of daily living. This study provides specific information on the instrument's psychometric properties in different populations and supports clinicians in making informed decisions when choosing instruments for upper-limb evaluations.

Levels of Cognitive Functioning Assessment Scale: Italian cross-cultural adaptation and validation

STUDY DESIGN

Cross-sectional study.

OBJECTIVE

To develop an Italian version of the Levels of Cognitive Functioning Assessment Scale (LOCFAS) and examine its reliability and validity.

SUBJECT

Patients with acquired brain injury in an early post-coma state.

METHODS

The original scale was translated from English to Italian using the guidelines set forth in the Translation and Cultural Adaptation of Patient Reported Outcomes Measures-Principles of Good Practice. Intra-rater reliability was examined using the intraclass correlation coefficient (ICC). Concurrent validity was evaluated using Pearson's correlation coefficients with some of the functional and disability components of the International Classification of Functioning, Disability and Health (ICF), excluding environmental factors.

SETTING

The highly specialized neurorehabilitation department of "San Raffaele" Hospital, Cassino.

RESULTS

The Italian version of the LOCFAS (LOCFAS-I) was administered to 38 subjects from May 9, 2017 to August 31, 2017. The mean ± SD of the LOCFAS-I score was 3.05 ± 1.88. All LOCFAS-I items were either identical or similar in meaning to the original version's items. Test-retest reliability (ICC) was 0.996 (p<0.01). The Pearson correlation coefficient of the LOCFAS-I scores with some of the functional and disability components of the ICF was > 0.536 (p<0.01).

CONCLUSIONS

The LOCFAS-I was found to be reliable and a valid measurement tool for the assessment of cognitive functioning post-coma in the Italian population.

Evaluation of physiotherapy and speech therapy treatment in patients with apraxia: a systematic review and meta-analysis

Apraxia affects 20% of the right brain-damaged patients and 50% of the left brain-damaged patients. This disorder of motor programming reduces patients' independence and there are few guidelines on the rehabilitative treatment in the physiotherapy and speech therapy field.The aim of this study was to assess which therapeutic interventions are the most effective in stroke patients with apraxia in considering the mentioned purviews. Four databases were systematically searched in order to detect all available studies investigating the physical and speech rehabilitation of patients. The literature research produced five studies including 168 patients for the physiotherapy and 50 for speech therapy fields; two were eligible for meta-analysis. Quality was rated with Jadad, PEDro scale and Cochrane Risk Of Bias Tool. Both for physiotherapy and speech therapy fields, the RCTs interventions obtained statistically significant results for outcomes of interest. Despite this, it is still not possible to determine the best approach due to the low number of patients involved, the lack of maintenance of the results at follow up and the timing of the revaluation period being very short to confirm the efficacy of treatments.

Development and validation of a new mealtime assessment tool (MAT) for patients with dysphagia: A cross sectional study

PURPOSE

This study aimed to create a new quantitative and qualitative Mealtime Assessment Tool (MAT) to be administered by the not institutional caregiver to explore the dysphagic patient's mealtime behavior.

METHODS

The development and validation process consisted of three steps: firstly, identification of items for the questionnaire, then pilot testing phase of the first version of the instrument and finally a psychometric evaluation in which the test was administered to the target population (adult inpatients with diagnosed and undiagnosed oropharyngeal dysphagia).

RESULTS

A factorial analysis explained 51% of the variance and grouped the 12 items of the scale into three categories that defined: a) structural setting and compliance at mealtime, b) behavioral attitude at mealtime, c) structural setting as a function of possible distractibility. The concurrent validity using the Dysphagia Outcome Severity Scale and Three Oz Water Swallow Test, as the gold standard, was r =0.01. Cronbach's alpha was 0.709. Stability test-retest reliability had ICC values of 0.980 p=0.01. The ROC curve using as state variable the De Pippo test as a dichotomius variable showed the under-curve area as 0.830 (95% CI, 0.763 to 0.897).

CONCLUSIONS

The validation process led to the conclusion that the MAT is a valid, reliable and stable scale for caregivers.

Examining Reliability and Validity of the Jebsen-Taylor Hand Function Test Among Children With Cerebral Palsy

Manual dexterity has strongly predicted functional independence for daily life activities among children with cerebral palsy (CP). The Jebsen-Taylor Hand Function Test (JTHFT) is the most widely used assessment tool for exploring manual dexterity in the CP population, though no research has yet examined its psychometric properties for this use. This cross-sectional study explored the validity and internal consistency of the JTHFT in an Italian sample of inpatient and outpatient children with CP aged between 6-18 years (35 girls and 49 boys). We calculated internal consistency with Cronbach's alpha and tested validity against the Manual Ability Classification System (MACS) using Pearson's correlation coefficient. To better understand how the JTHFT compares with different levels of the MACS, we performed dominant hand timing variability for each test item. Results showed excellent internal consistency with a Cronbach's alpha of .944 and .911, respectively, for nondominant and dominant hands. There was also a statistically significant positive linear Pearson's correlation coefficient between the JTHFT and the MACS (p < .01). We observed high variability in writing performance (Item 1 of the JTHFT) within this sample for each level of the MACS. This study confirms that the JTHFT is a valid assessment tool when used in children with CP aged 6-18 years.

Validation of the Pediatric Evaluation of Disability Inventory in an Italian Population with Autism Spectrum Disorder: a Cross-Sectional Study

OBJECTIVES

To measure psychometric properties of the Italian version of the Pediatric Evaluation of Disability Inventory (PEDI-I) in a population with Autism Spectrum Disorder (ASD).

METHODS

The PEDI-I was administered to different children with ASD. The internal consistency was examined by using Cronbach's Alpha, while the intraclass correlation coefficient (ICC) was used to investigate both inter-observer and intra-observer reproducibility. Its concurrent validity was evaluated with the Italian version of the Barthel Index.

RESULTS

The PEDI-I was administered to 60 children with a diagnosis of ASD. Cronbach's Alpha showed statistically significant values (.885-.965). Inter-observer and intra-observer investigations confirm the reproducibility of the scale with a range of high and very high parameters. The Pearson Correlation Coefficient with the Barthel Index showed significant data for all PEDI-I subscales with a p<0.01.

CONCLUSIONS

The PEDI-I showed good psychometric properties and it is possible to confirm its validity and reliability in ASD population. However, for better understanding of how PEDI-I works in clinical practice, further researches are recommended.

Hearing loss in children with congenital cytomegalovirus infection: an 11-year retrospective study based on laboratory database of a tertiary paediatric hospital

Congenital cytomegalovirus infection is considered the main cause of infantile non-genetic neurosensory hearing loss. Although this correlation was described more than 50 years ago, the natural history of internal ear involvement has not yet been fully defined. Hearing loss is the most frequent sequela and is seen in a variable percentage up to 30%; the hearing threshold is characterised by fluctuations or progressive deterioration. The purpose of this study was to evaluate the prevalence of hearing loss in cases of congenital CMV infection from Modena county, starting from the database of the microbiology and virology reference laboratory. All children undergoing urine testing for suspected CMV infection or viral DNA testing on Guthrie Card in the period between January 2004 and December 2014 were enrolled in the study. Family paediatricians were contacted and asked about clinical information on the possible presence at birth or subsequent occurrence of hearing loss, excluding cases where this was not possible. The results showed an annual prevalence of congenital cytomegalovirus infection among suspected cases that was stable over time despite the progressive increase in subjects tested. The prevalence of hearing loss was in line with the literature, whereas in long-term follow-up cases of moderate, medium-to-severe hearing loss with late onset were not detected. The introduction of newborn hearing screening in the county has allowed early diagnosis of hearing loss at birth as non-TEOAE-born births underwent a urine virus test. Moreover, despite all the limitations of the study, we can conclude that European epidemiological studies are needed to better define the relationship between congenital CMV infection and internal ear disease as the impact of environmental and genetic factors is still not entirely clarified.

Psychometric properties of the Italian version of the Barthel Index in patients with Parkinson's disease: a reliability and validity study

The Barthel Index (BI) is used in Italy to measure the severity of disability and to identify patients suitable for admission to rehabilitation units. The objective of this psychometric study was to validate the Italian version of the BI in a population of patients with Parkinson's disease (PD). The study was conducted at three neurological and rehabilitation centres in Rome, Italy. The BI was administered to outpatients with PD. The reliability of the scale was assessed using Cronbach's alpha for internal consistency; the intra-class correlation coefficient (ICC) was used to measure its intra- and inter-rater reliability. Pearson's correlation coefficient was calculated to evaluate its validity, comparing it with the Parkinson's disease Questionnaire (PDQ-39), the Italian version of the Geriatric Depression Scale (GDS), the Hospital Anxiety and Depression Scale (HADS), and the Short Form 36-Health Survey Questionnaire (SF-36). The BI was administered to 94 patients with PD. The psychometric properties measured were significant: Cronbach's alpha was 0.866 and the ICC for intra- and inter-rater reliability was 0.998 and 0.993, respectively. Pearson's correlation coefficient showed good correlation with the PDQ-39, GDS, HADS and SF-36 (p < 0.01). The BI is a valid and reliable tool for measuring disability in a PD population.

Seven-day Storage of Single Donor Platelets in Polyolefin Bags: Clinical, Biochemical, Morphological and Microbiological Evaluation

We compared the in vitro and in vivo function of fresh and stored platelet concentrates (PCs) collected by an automated continuous-flow blood cell separator (CS 3000 Fenwal) in a closed-system apheresis kit in order to evaluate the possibility of extending the storage time to seven days with the polyolefin container (PL-732). The initial 220 ml platelet volume (5.14 ± 1.23 x 1011) was divided into two parts. Half was transfused and the other half was stored for 7 days. All cultured units were negative for bacterial contamination. Mean counts for fresh and stored platelets were respectively 2.34 ± 0.59 and 2.17 ± 0.50 x 1011/100 ml of PCs (mean recovery 88.7 ± 11.9%). The pO2 levels were maintained during storage (179.9 ± 30.5 mmHg) but pCO2, pH, LDH, osmolality, glucose consumption, bicarbonates, ATP, and osmotic stress values changed significantly after 7 days storage. From a clinical point of view, in 14 patients receiving a total of 38 PC transfusions no statistically significant change in corrected post-transfusional levels was observed between fresh and stored PC. Biochemical and morphological data and clinical results suggest that PCs collected with CS-3000 blood cell separator in a closed system and stored for 7 days in polyolefin bags (PL-732) can be satisfactorily employed in clinical practice.

Enrichment of Marrow Hemopoietic Progenitor Cells using a Blood Cell Processor

A total of 93 bone marrows (BM) from normal donors and patients were processed using the IBM-COBE 2991 blood cell washer to produce a concentrated buffy coat (BC) for either bone marrow transplantation (BMT) or cryopreservation for subsequent autologous BMT. The reduction in volume was 73.3 ± 8.5% and nucleated blood cells (NBC) recovery was 87.1 ± 9.1% of original marrow. Red blood cell (RBC) and platelet (PLT) contamination was reduced 64.5 ± 10.9% and 41.2 ± 24.1%, respectively. Clonogenic activity indicated that the NBC fraction was highly enriched in hematopoietic progenitor cells (> 100%) as assessed in vitro (CFU-GM). Results were not affected by diagnosis, initial marrow volume or cell count of the BM suspension. We conclude that this is a simple and reproducible method using blood bank, facilities and permits BC preparation from BM without significant loss of hematopoietic progenitor cells.

Cross-cultural adaptation and validation in the Italian population of the wolf motor function test in patients with stroke

Motor impairments of the upper extremities affect approximately 60% of stroke patients. Rehabilitation is extremely important and can make it possible to identify which manual function is causing difficulty for the patient and hindering daily activities. The Wolf Motor Function Test (WMFT) was recently highly recommended as one of several outcome measures that assess limitations of activities with a high level of psychometrics and clinical utility. The objective of this study was to translate and culturally adapt the WMFT for the Italian population (WMFT-IT) and examine its reliability and validity in Italian post-stroke adults with chronic hemiplegia or hemiparesis. The original scale was translated into Italian and culturally adapted in accordance with international guidelines. Its internal consistency and stability were examined using the Cronbach's alpha (α) coefficient and the intra-class correlation coefficient (ICC), respectively. Its concurrent validity was evaluated using the Pearson's correlation coefficient to compare the instrument with the Italian version of the Jebsen-Taylor Hand Function Test and the Disabilities of the Arm, Shoulder and Hand outcome measure. All WMFT-IT items were either identical or similar in meaning to the items in the original version. The WMFT-IT was administered to 24 subjects. Cronbach's α was 0.91 and 0.98 for the time and performance subscales respectively, and the ICC for test-retest reliability was 0.99. Pearson's correlation coefficients of the time subscale and the performance subscale both showed significant positive correlations (p <0.01). The WMFT-IT was found to be reliable and a valid outcome measure for assessing function and quality of movement of the upper extremities in post-stroke adults in the Italian population.

Intrapartum GBS screening and antibiotic prophylaxis: a European consensus conference

Group B streptococcus (GBS) remains worldwide a leading cause of severe neonatal disease. Since the end of the 1990s, various strategies for prevention of the early onset neonatal disease have been implemented and have evolved. When a universal antenatal GBS screening-based strategy is used to identify women who are given an intrapartum antimicrobial prophylaxis, a substantial reduction of incidence up to 80% has been reported in the USA as in other countries including European countries. However recommendations are still a matter of debate due to challenges and controversies on how best to identify candidates for prophylaxis and to drawbacks of intrapartum administration of antibiotics. In Europe, some countries recommend either antenatal GBS screening or risk-based strategies, or any combination, and others do not have national or any other kind of guidelines for prevention of GBS perinatal disease. Furthermore, accurate population-based data of incidence of GBS neonatal disease are not available in some countries and hamper good effectiveness evaluation of prevention strategies. To facilitate a consensus towards European guidelines for the management of pregnant women in labor and during pregnancy for the prevention of GBS perinatal disease, a conference was organized in 2013 with a group of experts in neonatology, gynecology-obstetrics and clinical microbiology coming from European representative countries. The group reviewed available data, identified areas where results were suboptimal, where revised procedures and new technologies could improve current practices for prevention of perinatal GBS disease. The key decision issued after the conference is to recommend intrapartum antimicrobial prophylaxis based on a universal intrapartum GBS screening strategy using a rapid real time testing.

Prevention of group B streptococcal neonatal disease revisited. The DEVANI European project

The purpose of this paper was to present the current knowledge on the prevention of group B streptococcus (GBS) neonatal infections and the status of prevention policies in European countries and to present the DEVANI pan-European program, launched in 2008. The aim of this program was to assess the GBS neonatal infection burden in Europe, to design a new vaccine to immunize neonates against GBS infections, to improve the laboratory performance for the diagnosis of GBS colonization and infection, and to improve the methods for the typing of GBS strains. The current guidelines for GBS prevention in different countries were ascertained and a picture of the burden before and after the instauration of prevention policies has been drawn. After the issue of the Centers for Disease Control and Prevention (CDC) guidelines, many European countries have adopted universal screening for the GBS colonization of pregnant women and intrapartum prophylaxis to colonized mothers. Nevertheless, some European countries continue advocating the risk factor approach to GBS prevention. Most European countries have implemented policies to prevent GBS neonatal infections and the burden of the disease has decreased during the last several years. Nevertheless, further steps are necessary in order to develop new strategies of prevention, to improve microbiological techniques to detect GBS colonization and infection, and to coordinate the prevention policies in the EU.

Positive and negative emotional arousal increases duration of memory traces: common and independent mechanisms

We compared the ability of positive and negative emotional arousal to increase the duration of consolidated memory traces. Positive arousal was modulated by manipulating the motivational salience of the testing cage of an object recognition test. Negative emotional arousal was modulated by manipulating shock levels in a step-through inhibitory avoidance (IA). Mice trained in either a high (chocolate-associated) or a low (inedible object-associated) emotionally arousing cage showed discrimination of a novel object 24 h after training, but only mice trained in the more arousing cage showed retention 96 h after training. Mice trained with either low (0.35 mA) or high (0.7 mA) shock intensities showed increased step-through latencies when tested 24 h after training, but only mice trained with the higher shock intensity showed retention of the IA learning 1 week after training. Administration of the phosphodiesterase type IV inhibitor Rolipram immediately after training in the two low arousing conditions increases duration of both responses.

A clinical case of necrotizing sialometaplasia and conjunctival hemorrhage

The first case reported in the literature of a rare disease called necrotizing scialometaplasia (NS), dates back to 1973 when Abrams et al. described the main histological features of this disease. In this article we describe the rare clinical case of a young woman came to our observation for a double ulcer in the middle portion of the hard palate, aching, that histological examination showed compatible with a diagnosis of NS and preceded his appearance a haemorrhagic conjunctival suffusion left. We have provided a complete description of all the investigations in which the patient underwent and its treatment. We have also outlined the major etiological hypotheses of SN, histological features that point to a correct diagnosis, clinical features and prognostic and finally we reflected on the rare and interesting overlap in clinical manifestations palatal and conjunctival those trying to find a possible explanation.

Neonatal bacterial meningitis

Neonatal bacterial meningitis (NM) continues to be a serious disease with an unchanging rate of adverse outcome of 20-60%, despite a worldwide decline in mortality. The 3 major pathogens in developed countries are: Group B streptococcus, gram negative rods and Lysteria monocytogenes. Signs and symptoms of NM may be subtle, unspecific, vague, atypical or absent. In order to exclude NM, all infants with proven or suspected sepsis should undergo lumbar puncture. Positive culture of cerebrospinal fluid may be the only way to diagnose NM and to identify the pathogen, as CSF parameters Smay be normal at early stages and NM may occur frequently (up to 30% of cases) in the absence of bacteraemia. When NM is suspected, treatment must be aggressive, as the goal is to achieve bactericidal concentration of antibiotics and to sterilize CSF as soon as possible. Antibiotics should be administered intravenously, at the highest clinically validated doses. Empiric antibiotic treatment should include agents active against all main pathogens; currently the recommended empiric treatment of NM is ampicillin, plus an aminoglycoside and a third-generation cephalosporn. Therapy should be reassessed after cultures and antibiotic susceptibility is available. Prevention of neonatal sepsis, early recognition of infants at risk, prompt treatment and future adjunctive therapies will improve prognosis. Finally, we present the first preliminary Italian data on GBS meningitis. Data are obtained from an area-based study conducted In Emilia-Romagna during 2003 to 2009.

Use of cardiac troponin T rapid assay in the diagnosis of a myocardial injury secondary to electrical cardioversion

BACKGROUND AND HYPOTHESIS

This study was carried out to determine whether cardiac troponin T test in rapid assay gives positive results in patients previously submitted to cardioversion or electrical defibrillation.

METHODS

Forty patients with supraventricular tachyarrhythmias lasting no more than 2 days were treated with electrical cardioversion. The total creatine phosphokinase (CPK)-MB isoenzyme and troponin T in rapid assay were measured at baseline and at 6, 12, and 24 h thereafter.

RESULTS

Total CPK baseline levels were normal in all cases; within 4 h, the serum CPK levels increased by 98%, at 6 h by 111.5%, at 12 h by 168%, and at 24 h by 225% (p > 0.01). The CPK-MB isoenzyme showed no percentage increase of total CPK higher than 5%, measured at 6, 12, and 24 h after the shock, independent of the number of attempts of cardioversion. The troponin T test was also negative in all cases at baseline and at 6, 12, and 24 h after cardioversion.

CONCLUSION

We conclude that the absence of elevations in CPK-MB levels and cardiac troponin T levels matched clinical and electrocardiographic results showing absence of myocardial damage after electrical cardioversion.

Hereditary diffuse gastric cancer and E-cadherin: description of the first germline mutation in an Italian family

AIMS

Germline mutation of the E-cadherin gene (CDH1) accounts for the Hereditary Diffuse Gastric Cancer (HDGC) syndrome. Fourteen pedigrees with Diffuse Gastric Cancer that fulfilled the International Gastric Cancer Linkage Consortium (IGCLC) criteria were selected and screened for CDH1 germline mutations.

METHODS

The entire coding region of the CDH1 gene and all intron-exon boundaries were analyzed by direct sequencing in the 14 families fulfilling the IGCLC criteria. E-cadherin immunohistochemical expression was evaluated on tumour as well as normal formalin-fixed paraffin embedded tissues.

RESULTS

A novel germline missense mutation was found. It was a single C-->T substitution in exon 8, resulting in a transition of CCG-->CTG (C1118T; Pro373Leu) demonstrated in the proband and her brother. At immunohistochemical analysis, the staining intensity was reduced and considered weakly positive (15%).

CONCLUSIONS

The first CDH1 germline mutation of an Italian family is herein reported. The present missense mutation has never been described so far.

[Prophylaxis of group B streptococcal infections in the birth centers of Emilia Romagna]

OBJECTIVES

In the last decade several guidelines for prevention of neonatal group B streptococcal invasive disease have been published, mainly based on administration of intrapartum antibiotics. The spread of such recommendations yielded a reduction of the early-onset disease. The aim of the study was to investigate the practices for prophylaxis of neonatal infection in our region during the 2000 and to standardize them according to the new available evidence.

METHODS

We conducted a multicenter study in Emilia Romagna, sending by mail a detailed questionnaire to the 28 birth centers of our region.

RESULTS

Fifteen centers answered to the questionnaire. The practices were often differing from the recommendations of scientific societies. The most sensitive methods to identify colonized women were not widely used. Colonized infants were frequently treated with antibiotics and discharged later from the nursery. The incidence of neonatal invasive diseases was low, but most centers did not regularly collect a blood culture before antibiotic treatment is started.

CONCLUSIONS

Repeated meetings among centers promoted the diffusion of information, the implementation of a shared protocol and the spread of the practices. The results of such meetings will be evalued in the next months.

Diffusion-weighted MRI of maple syrup urine disease encephalopathy

We report the case of a newborn child with maple syrup urine disease (MSUD), diagnosed at 10 days of life. Diffusion-weighted echoplanar MRI showed marked hyperintensity of the cerebellar white matter, the brainstem, the cerebral peduncles, the thalami, the dorsal limb of the internal capsule and the centrum semiovale, while conventional dual-echo sequence evidenced only a weak diffuse T2 hyperintensity in the cerebellar white matter and in the dorsal brainstem. The apparent diffusion coefficient (ADC) of these regions was markedly (>80%) decreased. Therefore, in agreement with current hypotheses on MSUD pathogenesis, MSUD oedema proves to be a cytotoxic oedema. Diffusion-weighted MRI may be a valuable tool, more sensitive than conventional spin-echo techniques, to assess the extent and progression of cytotoxicity in MSUD, as well as the effectiveness of the therapeutic interventions.

[Sepsis caused by Corynebacterium xerosis in neonatology: report of a clinical case]

The pathogenicity of the nondiphtheria corynebacteria, most commonly known as coryneform bacteria in humans has been recognized in the last two decades. Corynebacterium xerosis is part of the normal flora of the skin, nasopharynx, conjunctives and it has recently been isolated from vaginal swabs. During the last few years, there has been an increased number of case reports claiming an association of C. xerosis with diseases, like septicemia, endocarditis, pleuropneumonia, peritonitis, osteomyelitis, septic arthritis, mediastinitis, meningitis, ventriculitis specially in immunocompromised patients or surgical patients. Infections due to C. xerosis have been reported rarely in newborn. We report a case of sepsis due to C. xerosis in a newborn without evident immunodeficiency. Our case further support the recognition of C. xerosis as a human pathogen and reinforces the fact that it should not be routinely considered as a contaminant.

Overall vigilance and sustained attention decrements in healthy aging

Age differences in sustained attention were investigated using a high-event rate digit-discrimination task at 6 levels of stimulus degradation (lasting 8.1 min each). Twenty-one young, 21 middle-aged, and 20 old healthy subjects were studied. Overall sensitivity (d') was equivalent in all groups. Although all subjects showed a sensitivity decrement over blocks, there were no age-related differences in sustained attention capacity. All subjects had larger decrements in d' over blocks at higher degradation levels. However, the performance decrement at higher degradation levels was equivalent in all groups, indicating similar decrement rates in sensitivity with increasing demands on effortful processing. These results indicate that overall levels of vigilance and the ability to sustain attention over time are equivalent in all groups under conditions requiring both automatic (low-degradation) and effortful (high-degradation) stimulus processing.

Nitric oxide synthases in normal and benign hyperplastic human prostate: immunohistochemistry and molecular biology

The expression of nitric oxide synthase (NOS) isoforms has been investigated in normal (three subjects) and benign hyperplastic prostate (ten patients) by immunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR). The inducible NOS (iNOS or NOS-2) is not detected in normal prostate, while it is expressed in the prostate of all benign prostatic hyperplasia (BPH) patients, even in the absence of prostatitis or systemic signs of an inflammatory condition. This suggests that sex hormones may be involved in iNOS induction and that there may be a role for NO in the pathogenesis of BPH. Constitutive NOSs (nNOS and eNOS) are expressed in both normal and hyperplastic prostate and are co-expressed in epithelial cells. eNOS, however, is present mainly in the basal layer cells; nNOS seems abundantly expressed in the more superficial cells of the affected prostate. This indicates that the switching between the two constitutive isoforms may be part of the usual process of cell differentiation from the basal to the secretory layer of the epithelium.

Imagery and hypnotizability revisited

The objective of this study was to correlate computer-generated imagery tasks and a self-report measure of imagery ability with hypnotizability, hypothesizing that computer-generated imagery tasks would be better predictors of hypnotizability than will the self-report measure. Hypnotizability of 43 subjects was assessed using the Hypnotic Induction Profile and the Stanford Hypnotic Susceptibility Scale, Form C. Imagery ability was assessed by the Visual Vividness Imagery Questionnaire (VVIQ) and by computer-generated imagery tasks measuring the ability to generate, maintain, and transform images. Although there was no correlation between the VVIQ and hypnotizability, the less hypnotizable subjects made twice as many mistakes in the spatial imagery tasks than did the more hypnotizables, but this difference was not statistically significant. The relationships among hypnotic performance, hypnotizability, and imagery functions are complex.

Face and word memory differences are related to patterns of right and left lateral ventricle size in healthy aging

Discrepancy between face word memory was measured with experimental continuous recognition tests and compared with right-left asymmetry of lateral ventricle size, measured with volumetric x-ray computed tomography, in 10 young and in 10 elderly subjects. All were right-handed and healthy. Old subjects differed significantly from young subjects on face but not word memory. Old subjects had significantly larger lateral ventricles than did young subjects and more lateral ventricle asymmetry. No group trend toward disproportionate age-related enlargement of the right ventricle relative to the left was noted. In old subjects, however, lateral ventricle asymmetry correlated with face-word memory discrepancies in the expected direction, worse word than face memory being associated with disproportionate enlargement of the left lateral ventricle. These correlations were not significant in young subjects. These results suggest that the group trend toward disproportionate nonverbal/visual, as opposed to verbal, age-related memory differences is not associated with a group trend toward disproportionate enlargement of the right ventricle. Individual deviations from the normative pattern of age-related ventricle enlargement, however, are associated with different patterns of material-specific memory changes.

Clinical pharmacokinetics of arecoline in subjects with Alzheimer's disease

OBJECTIVE

To study the pharmacokinetics and pharmacodynamics of intravenously administered arecoline in subjects with Alzheimer's disease.

METHODS

Plasma arecoline concentrations were measured during and after high-dose (i.e., 5 mg intravenously over 30 minutes) and up to 2 weeks of continuous multiple-dose steady-state intravenous infusions of arecoline in 15 subjects with mild to moderate Alzheimer's disease. During multiple-dose infusions, the dose of arecoline was escalated from 0.5 to 40 mg/day. Psychometric tests were administered at baseline and every other dose to determine an "optimal dose" for each subject. This dose then was administered for 1 week using a randomized, placebo-controlled, double blind, crossover design. Plasma drug concentrations were measured by GC-MS.

RESULTS

The optimal dose of arecoline varied fourfold across subjects (4 mg/day, n = 6; 16 mg/day, n = 3) with mean plasma half-lives of 0.95 +/- 0.54 and 9.3 +/- 4.5 (SD) minutes. Clearance and volume of distribution were 13.6 +/- 5.8 L/min and 205 +/- 170 (SD) L, respectively. At the dose that optimized memory, the mean plasma level was 0.31 +/- 0.14 (SD) ng/ml, and it predicted the optimal dose in all subjects.

CONCLUSIONS

Because optimal dose variation is due to differing plasma kinetics, the plasma arecoline level measured at a single infusion rate can be used to choose the optimal dose for memory enhancement in patients with Alzheimer's disease.

Differential response to the cholinergic agonist arecoline among different cognitive modalities in Alzheimer's disease

Nine patients with possible or probable dementia of the Alzheimer type were tested on nine cognitive tests prior to (two times) and during continuous intravenous administration of five different doses of the muscarinic cholinergic agonist arecoline (1, 4, 16, 28, and 40 mg/day). The present analysis examined whether improvement on cognitive testing for each patient during arecoline treatment was most likely to occur at the same dose for all tests or whether different test scores improved at different doses of arecoline. Results indicated there were significant differences among tests in the dose at which most patients showed improved cognitive performance. These differences may have therapeutic significance, as verbal ability tended to improve at low doses of arecoline, whereas attention and visuospatial ability tended to improve at higher doses of arecoline.

Brain mechanisms in human classical conditioning: a PET blood flow study

Five healthy male subjects participated in a classical conditioning experiment, and positron emission tomography (PET) was used to compare regional cerebral blood flow before and after conditioning. The subjects participated in three different experimental phases. In the first (habituation) phase they listened to 24 repetitions of a tone with random intervals. In the second (acquisition) phase, the tone was paired with a brief shock to the wrist. In the third (extinction) phase, the tone was presented alone again. 15OPET scans were taken during the habituation and extinction phases. Because the habituation and extinction phases were similar, any difference in blood flow to the tones presented during extinction probably reflected conditioning that occurred during the acquisition phase. Statistical parametric mapping (SPM) analysis of the PET data showed significantly increased activation in the right hemisphere in the orbito-frontal cortex, dorsolateral prefrontal cortex, inferior and superior frontal cortices, and inferior and middle temporal corticies. The only activated areas in the left hemisphere were area 19 and the superior frontal cortex. The results are interpreted as evidence for the involvement of cortical areas in human classical conditioning.
